I will. I'll keep this post going as I do things to the drive train.
Thanks man... I appreciate this
I'm bout to attempt to do my wire harness. some guy that does this wire harness around here Wanted to charge 1200 plus taxes he said he had to order a new harness he always uses on swaps but I been reading ur post and I'll just save me that money n doit
Like you did
So you splice the 5.3 harness and sorder it to the 97 harness? Both ecu s gotta be in the truck?
Ya just splice in to it. I just have the 5.3 ecu. You will have to add some wires if your going with the throttle by wire.
Hey Quick Question
What headers did you use?
I am using the Schoenfeld LS conversion headers for the 88-98 in my 95 2wd and they fit and work great, but I understand there are issues on a 4wd.
Ok ima get me a set of them
I'm working on a 97
But I only get to work on once every 2 weeks since I drive over the road
I used 99+ shorty headers. Will have longtubes soon.
The wiring pinouts for the swap. When comparing them to the lt1swap.com the pinouts for a 411 pcm they don't match. Plus don't you have to splice in wires got the ignition Control?
