I need you guys help. I bought a 1998 s10 with a bad 4.3 but it came with a 5.3 btr cam and a new psi standalone harness. I'm going to install the 5.3 in the s10 but I think the harness is not the correct one Because I want all the factory gauges to work so a standalone harness is not going to work with the bcm I don't think. I have the junkyard5.3 harness that came with the motor I'm not sure what it came out of I also have the 4.3 s10 harness, I have never done any harness work so my question is what do I need to do to make this work use the psi harness or the junkyard harness, is there someone I can send it to for the work or is it something I can do.Thanks again for any help or advice.
Thanks,Shannon

Might try these folks. I've never used them nor know anyone who has, or anything about them.
