Wiring questions...

Post by gtn116 »

Setup is ng block, 7a head. I have most of the wiring figured out, just need to know what I'm looking at here. The 2 sensors in front of the mount arm, what are they and how do I wire them?

single pin sensor is the oil pressure switch, two pin sensor is the oil pressure gauge sender. Both should be wired to your cluster

5ktq doesn't have oil temp or pressure gauge so they're there to tell the auto check if the oil pressure drops to a low enough level. If so it'll kick on the oil warning light. You'll wire them in the same way your mc1 pressure senders were wired. Just treat the 2 pin sensor as a 1 pin.

either way your oil pressure warning light is going to be blinking at you 24/7.
I'll get you the info to keep it from running 24/7. A wire has to be run from an injector output, to the auto check harness.

Personally I'd ditch the auto check and get some gauges... I used to be all about factory integration and making sure all the features worked, but, its just not worth the hassle anymore. A few intelligently placed warning lamps wired to the sensors of choice (oil pressure, coolant level, maybe low fuel level) and the aux gauge panel from a B3 90 or CQ is really all you need. I'm sure your eyes can tell you if you have a headlight out, your foot will let you know if your bomb has lost pressure or your arms will tire rather quickly if you've lost power steering ;-)
