Ls3/525

I have GM LS3/525 crate motor with the GM stand alone harness. The connector on the harness doesn't fit the oil sending unit or the MAP sensor. I think I can change the oil sending unit but not sure on the MAP sensor. Anybody else had this problem?

When did you get the harness and where did you get it from? I think the harnesses changed a few years ago, when GM moved to the newer style map sensors. We have used at least 12 GM harnesses in the last couple years, haven't had your problem. Post some pics of your sensors and connectors

GM made several changes through the years the the Gen IV engines. However, there are just a few changes to the electronics of their crate engines. Check out this page for pictures and this will help you identify which connector you need. We build pigtails and plug and play adapters depending on which sensor your harness has.

Thanks for the replys. May have this part of the harness figured out.
