Convert ETC to cable TB

[xtreme]

I am helping a customer that installed a 5.3 out of a 05 truck into a 83 pickup. Can I delete the Electronic throttle control and use a cable throttle body? There are other issues with the IAC ..etc.. Does anyone have any wiring information help for this conversion?

Yes. I have done this.

I just bolted on parts to the newer longblock and then used an Operating System that didn't have fly by wire. My engine was a 2004 LM4.

I changed the throttle body and wiring harness. I think most all of the sensors were the same. I think I played around with the steam tubes. It wasn't that bad. Small mods.

I don't think the 05 5.3L engines have a different crank reluxor than 2004 5.3L engines. You would have to ask.

I guess that you used a wiring harness and a 512 PCM. He was wanting to use the 1mb PCM. Is there a OS for the 12582605 PCM that supports the cable throttle body.

Did anyone come up with an answer or is it a case of buy a 512 ECU?

I bought a 6.0 out of an 06 van that was still cable throttle. I believe all the vans were cable throttle up to 06, if you found a file from a van it might have cable throttle. I thought I saw one on holdercrazy some time back.

here is one from holder crazy, it's for an 04 with a 6.0 but you could try a full flash, the pcm might accept it, if it does then just find a 5.3 of the same os and do a segment swap.

Is the IAC wiring the same as the red/blue plug LS1 pcm? I have it running and the ecu is attempting to control the idle but there is no response, no IAC movement, I notice the plugs are not interchangeable between pcms. All I have is wiring for the red/blue 512k connector pcm. I have the green/blue pcm 1mb.

I did a transplant a couple of months ago (2001 DBW Denali 6.0ltr into Jeep Wrangler) The owner "INSISTED" on a cable operated throttle body instead of the drive-by-wire.
I did a full re-flash on the Denali pcm using the OS from a 2001 Silverado 6.0 w/ cable throttle body
Located and pinned out the signal's for the TPS & IAC. Fired right up...
Also, I used the wiring harness from the Denali.

I am pretty sure the IAC and TPS pinouts are the same on the 1mb as they are on the 512K. tomorrow I can look at the schematic for an 04 or 05 van, and let you know.

That would be great.
