Uh, none. Edelbrock 4 bbl on a Performer manifold. Most of my truck is rather old school.

I did consider sticking with a normal binary switch, and wiring the compressor trigger to the fan controller, that way the fan would come on whenever the compressor was engaged. But the trinary switch seems to be a smarter way to run it.

Re: SkinnyG's '61 Apache
 

I'm having trouble locating a simple LP switch that can connect to my drier. Golly I've searched.

I may just run the Trinary I have on the low side, and use the factory High Pressure on the compressor itself - I don't expect the Low Pressure side is going to ever see the 377psi the switch will shut off at. I imagine the High Pressure switch will have done its job long ago.

Re: SkinnyG's '61 Apache
 

Often with carb & A/C, you use a "step up" solenoid on the throttle to raise the idle speed when the A/C is engaged.

Header wrap and a turbo blanket. If you've ever done insulation, you know how this feels on your skin. It took a full 50' roll for the down tube.

Ran the wires into the cab, had to cut the factory wiring opening a bit larger. I will likely use one of these split seals.

Chugging my way through details of the wiring

https://www.gwellwood.com/wordpress/...49-672x378.jpg

I made brackets that will attach to the steering colum bracket mounts, one for a fuse and relay box, and another for the drive-by-wire module.

Also added the OBD2 port, accessible but tucked out of the way.

Re: SkinnyG's '61 Apache
 

Nice detailed work. I’m always amazed by the bulk of the harness on a modern engine.

Re: SkinnyG's '61 Apache
 

Yes, a lot of detailed work, I'm also amazed at the amount of wires. Am very curious about progress.

Re: SkinnyG's '61 Apache
 

Wiring up the fuse/relay box I got off Amazon.

A bit of a challenge figuring out how I'm going to feed it all, and then I noticed the "optional equipment" in the American Auto Wire kit. The fuse box already has some high current circuits for things like Power Seats (I'll use for PCM), Power Windows (I'll use for Starter Relay), Cruise Control (don't need; done by PCM), AC (I need that), Fuel Pump (I need that).

This is actually super, super helpful!

Just excited to share, y'all.

Re: SkinnyG's '61 Apache
 

Wiring wiring wiring.

Finished up wiring the AC system.

Running wires to the starter and alternator.

Wiring the Classic Instruments gauge cluster.

Wiring an alarm system.

Wiring the OBD2 port.

No pictures, because it's just.....

Re: SkinnyG's '61 Apache
 

Exciting news!

I got the PCM to wake up, and my scan tool works. 5 codes, which are basically that the four O2s and the Evap are not connected.

Now to download the tune with HPTuners.

Re: SkinnyG's '61 Apache
 

Interestingly, I cannot run 3-bar on this P59 ECU.

Oh well.....

Re: SkinnyG's '61 Apache
 

Tidying up wiring under the hood and under the dash.

Heat-wrapped and ran the oil pressure and coolant temp wires for the Gauge Cluster.

Wired the courtesy lights.

Wired most of the alarm system, just need to add door pins switches.

Wired the Methanol Injection system, and placed but did not wire the "active" and "low juice" lights.

Wired the linelock. Need to pick a MOMSW. The kit came with one, but I don't want some nasty-butt button on the column shifter. I figure a foot switch would be classier. Do we NEED a light to tell me it's on? I mean, if I'm pressing the button and it's holding, it's probably on.

Need to get a replay for the cooling fan, but all the wires and connectors are now there.

Re: SkinnyG's '61 Apache
 

You sound busy and productive. What kind of courtesy light door switch are you going to go with? I'm not contributing a lot to your thread but I am always looking and reading your updates. Thanks for being consistent.

Re: SkinnyG's '61 Apache
 

THESE, once I figure out how to mount them.

Re: SkinnyG's '61 Apache
 

Finally decided on where the battery is going to go. For that, we need a mount!

First, in Fusion360:

Re: SkinnyG's '61 Apache
 

Cool video on the door latch mechanism...thanks for sharing.

For your battery tray, are you going to going to just mount it to a frame rail? Have you thought about one of the trays that drops down and then you can stow it back up once the battery is in it?

Re: SkinnyG's '61 Apache
 

This will be mounted to the frame rail. My intention with it is simply unbolt the whole bracket, drop it, and remove the battery.

Now cut it out of steel:

https://www.gwellwood.com/wordpress/...06-672x310.jpg

Re: SkinnyG's '61 Apache
 

My duallys setup is similar in intent but different in execution.

I bolted in two vertical uprights to have 'guides' for the batt box/tray to attach to.

The vertical uprights of the batt box/tray have 3/8" square nuts welded on the inside & the uprights bolted to the frame have slightly oversize 1/2" holes drilled in them.

You can muscle the batt (bolted into the box/tray) up into place by hand, but I found the AGM 34/78 batt was a wee bit heavier vs the standard lead/acid type I used for testing/validation.

I just put a fresh batt in & did the install w/a floor jack. Batt/box/tray slides up between the two frame guides. Adjust the height until I can get the 4x 3/8" bolts in place through the uprights into the box/tray. Tighten the hardware.

Your set-up is def more appealing to the eye vs. mine that's for sure. Having stuff laser or waterjet cut sure makes a difference.

Re: SkinnyG's '61 Apache
 

I actually recently ran across a thread where you shared the battery mount in your squarebody!

Re: SkinnyG's '61 Apache
 

I was going to mount it like your plan. I drilled the holes in the frame but found it cumbersome to get the bracket aligned w/the battery in place. So... Plan-B was mounting the 'guides' (1.5" x 3/16 angle) to the frame & running the box/tray bolts through the extended material on them. That made things much easier for me during install/removal validations.

Those AMG batteries feel a lot heavier (~10# ?) vs the lead/acid one I used initially for testing things.

Re: SkinnyG's '61 Apache
 

I am confident enough that I have the in-cab wiring done, that I wrapped the wiring.

A while back I bought one of these trinkets - freaking awesome for troubleshooting, but ALSO for initial testing of circuits:

https://s3.us-east-2.amazonaws.com/p...31_mmthumb.png

My truck came with a later 2-speed wiper/washer switch in the glovebox. I still have the 1-speed motor, but chucked the single-speed knob in the lathe and drilled a 3/16" hole through the center, and I machined a wee 3/16" "button" with a 1/4" shoulder, back drilled to fit the switch pin. Now I have a washer button!

The wipers do work - do they always operate a little "disconnected" from each other? I mean, they do their thing, I was just hoping for more symmetry.

I installed pin-switches for the courtesy lights (and alarm). That was tricky fishing the wire out through the hole. Works, anyway.

Also added a toggle switch for the air ride compressors. I mounted the switch inside the "ashtray" which I altered to house the air ride pressure gauges.

Ran alternator power and fuse panel power lines. Also bought a wack of 1ga wire to go to the battery, now that I've decided where to mount it.

Now I need it back in the air to run the wires underneath.

So much work; so much to do.

Re: SkinnyG's '61 Apache
 

They are doing a fantastic job,
I can't wait to see the truck running.

Re: SkinnyG's '61 Apache
 

I meant to powdercoat this, but had extra primer in the gun already:

Re: SkinnyG's '61 Apache
 

The truck came with a later windshield washer equipped wiper switch in the glopvebox. Good luck finding the 60-63 knob with a button. So I made one out of the existing knob:

https://www.gwellwood.com/wordpress/...24-672x378.jpg

Re: SkinnyG's '61 Apache
 

Thanks for showing me,
I was already wondering how my wiper system is supposed to work, I'll probably take over your patent. Thanks for that.

Re: SkinnyG's '61 Apache
 

Shoulder is 1/4" OD, pin (button) is 3/16" OD. Drilled in the back one size bigger than 1/16" to slip over the pin. No real measurements, cut to fit.

I still have the one-speed motor, but one of the pins is "hot" in both speed positions, so that one goes to the motor. The switch has two positions, but the speeds are the same between the two.

Re: SkinnyG's '61 Apache
 

Taillights are wired, as is a trailer light plug.

Battery mount is set in place near the back of the frame under the bed. Positive cable is done. Need more #2 wire for a decent ground.

Air ride compressors are now hooked up, run through a relay and a pressure switch. Looks like the pressure switch is 200PSI. That should be fun.

Stereo amp wiring is run up to the cab.

Re: SkinnyG's '61 Apache
 

Air lines, and stereo amp wire plumbed into cab. Need more DOT hose to plumb the air ride gauges.

Re: SkinnyG's '61 Apache
 

Air ride works. Two Viair 400's drain the battery fast. One air leak that I'll need to fix.

I ran -8 from the tank through a bulkhead fitting into the cab, into a log that splits into four 1/4" lines to manual valves, T'd to a gauge and run to each bag. It actually lifts quite satisfactorily. At 200psi in the tank.

Re: SkinnyG's '61 Apache
 

If you have a chance, I'd love to see that bulkhead/log fitting that you mentioned running into your cab with. That took a bit of mapping out on my truck as I ran each individual line inside my cab and trying to make sure the air lines were tucked out of the way from heat sources. Turned out fine but running one in to that splitter sounds like a good option.

Re: SkinnyG's '61 Apache
 

I need higher psi switches on my dually. The 120# limit is barely adequate for that heavy front end. It's on the current 'list-o-things'....

Re: SkinnyG's '61 Apache
 

Manual paddle valves for reliability and simplicity. Modified an -8AN bulkhead fitting to be a bit shallower. The gray is etching primer over the drilled holes. You are asking about the 4-into-1 manifold.

Windshield squirter didn't squirt.

Had to fabricate a new button - the button wasn't able to push far enough.

Here is what worked:

3/4" long
1/4"OD shoulder 1/16" thick, drilled 1/8"DIA only 1/8" deep
3/16" shaft for the remainder, rounded tip.

Drill the non-squirting knob 3/16" right through the center. And, like, use a lathe for this.

Re: SkinnyG's '61 Apache
 

Wiring is done.

Stereo is in and working

Cooling system holds water.

I've been over-thinking the engine oil cooler for three years. Today I bent up two little mounting brackets, and once they come out of the powder coating, the cooler will be ready to hang.

I -think- all I need to do is throw in a new battery, pressure test the fuel system, pressurize the oil system, and it should run.

I'm scared spitless.
