Bought this truck unfinished has the 09354896 pcm and Current Performance harness, I'm not finding a MAF connector anyone have a schematic of the pcm pins.thanks

 

http://lt1swap.com/wiringharness.htm should have the pinouts you are looking for. Your harness may have been built for speed density tune which would eliminate the maf.

 

Thanks for the very helpful information 1964ss I watched a video about the speed density tune so my next question is, is there a certain map sensor I should be using in accordance with the pcm and that harness?

 

Not sure which one u need. On my s10 I I use no maf. A gm 3 bar map and I separated the iat sensor wires and wired the iat separate into my charge pipe the pinouts are easy to follow

 

1. This harness has the iat connector,but there is no intake hose system on it yet been looking for a setup,not sure which type or brand that be best if you can help me here also this be great I really appreciate it thanks in advance

 

On a s10, there are so many different configurations, there is no 1 way. Is the radiator stock, or something from a different car or aftermarket? Where are the top/bottom hoses at? On mine, I just ordered from intake hoses, and configured a setup that works nicely. I made a heat shield from some sheet aluminum.
