Hey guys another stupid question. Does this electronic throttle pedal need a TAC (Throttle Accuator Control)? Or is it built in to the pedal or something seperate?

clinebarger · 01-04-2010, 04:28 PM

You need the pedal, throttle actuator control module, the harness between the two. when i get off ill take some pics of one.

Man, That would be great thanks

79gmc5.3 · 01-04-2010, 08:57 PM

Does anybody know year interchangeability for the 4l60E, 4l65E, and 4l80E are. The 6.0l is out of a 2003 Yukon Denali. Haven't decided which trans to use yet. Was told for a daily drive light towing the 4l60e is OK, the 4l65E is a beefed up 4l60E. and the 4l80E was used in the 3/4 ton trucks for heavy towing. Was also told that the 4l80E took more HP because of the large rotating mass of the internal components. I just need to know which years I can use. OK Ole guys of wisdom lets hear it.

Shon · 01-04-2010, 09:02 PM

Depending on what trans the PCM and harness you have is made to control depends on what your next options are. If the PCM controlled the 4l60e and has the wiring harness then that is the easiest thing. If you change to a different trans then you will need to change some of the pin placements and have the PCM segmented for the right trans.

I was going to let wait4me performance reflash my PCM and rework my stock harness. Do you know what years I need to stay with?

Shon · 01-04-2010, 09:31 PM

we use them all.....but if you are going to have him do it see if he has a preference.

clinebarger · 01-04-2010, 11:34 PM

I cleaned out my garage for my 39 and dont know where i put it. but do have some illustrations hope this helps

79gmc5.3 · 01-05-2010, 09:14 PM

Hey guys found a GM #12588924 Throttle Actuator Control will this work with my 2003 6.0L?

79gmc5.3 · 01-09-2010, 02:23 PM

Small update with a few pics. Motor is back together. got the gas pedal and TAC module. Motor mount plates are ordered, got the Harness and ECM boxed ready to ship to Wait4Me Performance . Will start pulling old engine in the next few days. Slow but any progress is a good thing!

Looking good! Looks like my customer is running into a few delays, but hopefully it won't be too much longer. I'm really looking forward to doing one of these swaps for myself!

menace121978 · 01-09-2010, 08:02 PM

looking good buddy! slow and steady!!

glock35ipsc · 01-15-2010, 01:48 PM

Dang, I'm just starting to get caught up on all the build threads. The swap is looking good! I like what your body guy did with the floor for the seats! I was kicking around using a set of those in my 85, but not sure I want to relocate the gas tanks after just buying 2 new ones!

I've though about building my own mounts and using a set of universal slides, that would set the seats a lot lower.

Lookin great, keep it up!

STOCKISH · 01-22-2010, 05:38 PM

Looking great, hows the progress?

Well it is slow but I think I have got everything together! Still need to send off my ECM and harness to Wait4me Performance, will try to do that next week. Just need a couple of warn days to pull the old engine out. But I am getting there.

STOCKISH · 01-22-2010, 11:32 PM

Awesome, dont forget the pics.

79gmc5.3 · 01-24-2010, 01:57 PM

Well I am just waiting on a good day to start. I took this pic because I love the way these engines look with the covers. Can't wait to see it sitting in the truck!!

menace121978 · 01-24-2010, 09:16 PM

looking good! be looking better in the frame rail!

but i'm not one in a position to say that!

79gmc5.3 · 01-25-2010, 08:28 PM

I asked this question in another thread but I will ask it here for those who are following this thread. Do I replace the oil cooler lines with the T-fitting for the oil pressure sending unit or do I tap the oil lines block?

Thealien · 01-25-2010, 08:53 PM

Some people remove the oil pressure sending unit from the back of the engine and use a 16mm X 1.5 to 1/8NPT adapter and use that for their oil pressure line/sender. The PCM doesn't need the oil pressure sender (from what everyone tells me). I am having a T made for that location so I can have both (I believe a scanner, Tuner and things like an aeroforce gauge can read the stock sender)

This is the adapter fitting

Aeroforce gauge

Sorry I didn't answer your question, just trying to give you options.

Thanks I have the Dakota Digital gauges so I need to use the sending unit for that. Will the ECM give an error code if the original sending unit is not there?

Thealien · 01-25-2010, 09:09 PM

I have been told no. Most of the harness people I talked to eliminate that connector.

Please don't take my word for it though and ask some others.

Do you know what thread your gauge requires? I'm pretty sure there will be a 16mmX1.5 adater to whatever it is.

Yes it is 1/8 npt. Wait4Me Performance is doing my harness and tune

Thealien · 01-25-2010, 09:12 PM

I just looked on their site and their senders are 1/8 NPT so that adapter will work if you don't need the factory sender.

Who is doing your harness/tune. Ask them

Shon · 01-25-2010, 09:34 PM

you dont need the Oil pressure sending unit, the PCM does not throw a code.
I used said adaptor and mechanical gauge.
