I'll be putting an '05 5.3L using an '04 computer and harness into my 68 chevy pickup. I'm doing some research for what to do about the whole throttle body/drive by wire "problem"

I think I'd like to just use the throttle by wire, but where do I get the pedal assembly? Is there a company that sells this, or should I find a used one from a wrecked truck? Also, what all is needed besides the pedal assembly?

Also, I heard that an Express Van of the same years still uses a cable and retains the same pinouts on the ECM. Does anyone have an '04 Express Van wiring diagram? I can get most others, but only the CNG express van is available????

Oh, I did some searching and didn't find these specific answers.

 

on the throttle pedal assy i got mine streight from the dealer... it only costs 76 dollors..

 

heck, that aint bad, got a part number

 

I am putting a 6.0l into my '70 Impala and I am keeping the DBW set up: along with the pedal, you also need the TAC module (small black box) and the short harness linking the 2. All this should come from the same vehicle as the computer.

 

Heres diagrams for '04 express van g2500 6.0L gas

 

hey thanks!

anyone have a picture of a TAC.

 

TAC module, harness and pedal from salvageyard $35. Had to modify pedal to conture with my tranny tunnel (Cut and weld). Get from a truck also.

 

cool, now i know what I'm looking for tomorrow at the salvage yards

 

the e-40 computer, like out of a 05 trailblazer and others, doesnt use a TAC modual..

 

My 2005 Suburban 5.3, PCM and harness uses one, but you got me what computer it is

 

You're going to need the pedal out of a corvette because it is stepped further away from the firewall. I also had to make a custom braket to mount it to get it far enough away so that it would go to 100% full throttle. Originally I got a pedal from a truck and there isn't anyway without making a HUGE adapter bracket that it would work.

i used one out of a 05 trailblazer... and modded the existing bracket for the stock pedal....looking back i also could of made a bracket from a 1 ton van (uhaul) work..

 

scored a pedal, TAC module and wire from the salvage yard on Friday

also got a 67 hood and grill!

 

Good deal. I had to cut my metal pedal lever and make a new one from angle iron. Lots of grinding to shape it right. Then weld it back on at right angle to clear tunnel and still be comfy on the ankle, and of course still be able to go full throttle. lots of times, over and over....Good luck with yours.

 

It's gonna be a long while before I get to adapting the gas pedal. Right now it's a bare frame

 

Ah, you should be able to get that back on the road by the weekend!!!

 

If I could sell my trans am, it would make it a lot easier.

As soon as it sells I got about $4000 worth of suspension/drivetrain parts to buy. Untill then not much is happening.

 

I still have to mount my setup that I got for a 2005 Chevy 2500. I can't wait to get it back from the painter.

 

Where did you find these???!? And can you get them for a 2007 Express/6.0L???
Thanks
Eddie

 

Does anyone know if the 07 5.3 uses the TAC module? Bought a drop-out and I'm not sure about the module.
