Nice take all the pictures you can they grow up faster than you can imagine.

Can anyone tell me how to setup the wiring to my brake switch? Iirc correctly the harness has a blue wire and a blue and white wire.

solidaxel · 06-13-2015, 01:44 PM

The stock switches are normally open until the brake is depressed and then the switch is closed sending 12VDC to the tail lights Via the steering column turn signals

jessemthompson · 06-13-2015, 08:13 PM

I should clarify what I meant on the brake switch. I am referring to the bp harness hooking into my brake switch for the torque converter lockup. There are two wires in the bp harness.

You need one of the brake switches with the 2 poles on it, one is for the brake lights and the other is for the harness/transmission - http://shop.bp-automotive.com/Electr...ch-TCC-001.htm

I just bought one from Amazon and put it in, its an ACDelco D862C, it worked great with the BP harness.

Just a couple of updates pics. Still have a little bit of work to do before I have her on the road.

Are the wires labeled? On a Gen4 engine, its usually one wire and is tapped into the wire on the brake switch that is hot when the brake pedal is depresses, the opposite of the older Gen 3 engines that use the dual contact switch.

Nice work. Looks Good.

jessemthompson · 06-20-2015, 04:14 PM

Thanks, got the part in order now. The radiator will be in Tuesday. Hopefully I can have it up by the end of next week.

jessemthompson · 06-23-2015, 09:37 PM

Finally got her running today! Still have to rap up the permanent fuel pump wiring, mounting the electric fans, routing the headlight wiring, mounting the bed and doing the fuel fill. I'd like to get the exhaust done this weekend.

Congrats..!!

jessemthompson · 06-25-2015, 07:17 PM

I have a vicious vacuum leak on my intake manifold. I found the culprit, I put some electrical tape over it just to stop it and that created a loud whistle. I am not sure what the piece on the manifold was or if it can be replaced. Some advise would be greatly appreciated.

solidaxel · 06-25-2015, 07:29 PM

There was a little nub there for a vacuum nose, I used it for my A/C vacuum attachment on my 78.
If you do not need a sorce for vacuum why can't you just plug it, maybe a screw with silicone on it

**mongocanfly** · 06-26-2015, 12:20 AM

Jess here is what mine looks like..its blocked from factory with that plastic stirrup thingy..like said before you might could tap it and put in a plug or barb fitting..but that plug don't look like it comes out but I don't know about that.

jessemthompson · 06-26-2015, 07:19 AM

Thanks guys. I think I'll attempt to plug it today and see what happens. When I covered it yesterday it created a whistle. It could've been leaking a small amount of air to cause that though. We shall see

solidaxel · 06-26-2015, 07:57 AM

You could always place a vacuum gauge on that fitting

jessemthompson · 06-26-2015, 09:48 PM

Starting to look like a truck again. I'm giving it a rest for the weekend. Doing a marriage retreat with the family. I'll be back at it Monday. Have to wrap up the details.

jessemthompson · 06-29-2015, 05:52 PM

Took the truck out on its first drive today. All seems fine except the trains starts out in 3rd gear and not first. I still have to troubleshoot this as its a bit of a headache

jessemthompson · 06-30-2015, 08:47 PM

I ended up mailing BP my ECM and TCM today. I tried to pull codes with a scan tool today and the scanner powers up but wouldn't link. Bill said the TCM is the first link up for the scan tool and he seems to think the place that sold me the setup may have just sent a non matching TCM. I hope this is the case. I had constant and switched power at the TCM connector.

**Mathew21** · 07-10-2015, 03:39 PM

Any updates yet?

eagleuh1 · 07-10-2015, 04:21 PM

What fuse/ relay center did you use.? On my 2005 5.3 , I used under hood fuse box for connecting stock harness. Unfortunately the tranny got its power from the interior fuse center on that model truck. Found out the hard way it wouldn't shift. Did some digging to find that out. God luck. Jim

jessemthompson · 07-10-2015, 05:55 PM

No updates yet and bp automotive built my harness and fuse box.

jessemthompson · 07-27-2015, 08:56 AM

Have a small update. I may have my issue figured out. There was a communication wire from the ECM into the TCM that wasn't making contact to the TCM. Just waiting to get it all hooked back up to test it. Then it's just a matter of having my exhaust system built and she should be road worthy. I have plans to take her to the rod run in gatlinburg tn this September.
