Good morning - hope everyone is going well.
I have an oil pressure gauge that looks like this one (not my car in picture but same sender), 1) I believe one terminal is for the actual pressure reading and one if for the warning light? 2) If that ^^^^ is correct does it matter which terminal is which? in other words is one terminal specific for the actual pressure reading? Thanks! |

There's no wire in the 914 harness for an oil pressure gauge, so if a PO hasn't put one in, you'll have to run one. If your car doesn't have/need heat, you can use the heater blower switch wire without too much trouble.

If your car doesn't have/need heat, you can use the heater blower switch wire without too much trouble. The relay board has an unused trace in it, and the pins on the harnesses are not filled. You can add a green/red wire to the engine harness, and to the chassis harness. I did this on Betty's car. I scavenged the wires out of a old junk 911 harness. It looks like it came that way. Clay |
