BlackSS04 Posted May 23, 2007 Report Share Posted May 23, 2007 (edited) I just recieved my tuned pcm core from wheatley, and i am trying to install it. I know were everything is and all, its just i cant get the wiring harness off of the PCM. you cant just manhandle it out of there, so how do you make it give way? And also, is there a procedure to start your truck after you get the tune in? do you just start it and your good?

rivierakid55 Posted May 23, 2007 Report Share Posted May 23, 2007 i dont remember it being hard to disconnect the pcm. ill check later as im putting my stock one in today for some in person tuning tonight. you may have to do the crank relearn procedure which zippy or someone else can explain better than i.

BlackSS04 Posted May 23, 2007 Author Report Share Posted May 23, 2007 alright, i finally got the pcm core off. do i have to put those orange gaskets around the corners of the new pcm? i noticed they were around the stock pcm and i am not sure if i need them or not.

BlackSS04 Posted May 23, 2007 Author Report Share Posted May 23, 2007 (edited) yes put them back they are seals to keep crap out off the pins it seems that those gaskets dont fit properly around the edges. did you have the same problem? i cant get the gaskets to stay down, the groves dont go deep enough.

wody Posted May 23, 2007 Report Share Posted May 23, 2007 yeah but after trying to put them on the pcm first i put them into the harness and then they seat themselves once you snug the bolts down. Quote Link to comment Share on other sites More sharing options...

brobradh77 Posted May 23, 2007 Report Share Posted May 23, 2007 There is a starting procedure where you try and start it and then leave the key on for 11 minutes and repeat 3 times and the third time it should staart if I remeber the procedure correctly.
