I recently swapped the 2000 PI engine into my 98 and my original wiring harness is wired for 2 sensors which plug into the manifold. I believe one goes to the computer and the other goes to the gauge cluster (correct me if I'm wrong). I have the one hooked up to the computer but the gauge isn't working and it's setting off my check engine light. I dont want to drill into the intake because it doesnt have the aluminum cross-over tube and I dont want to crack it. I tried splicing the wiring but I think the impedence is different in the two sensors and the light is still on. Anyone who has done the swap know how to fix this?
