('74 1.8 carbed so there's extra wires laying about)
my sender has 2 posts, one for a green wire (from the 12-pos plug in relay) and one red (i assume ?) for the idiot light. the harness wires lost their tags, so i'm not sure which one the red wire connects to, but there's a red/black one i am pretty sure is the one. can someone pls confirm? does it matter which post is used for which wire? thank you, thank you. paul |

if you have a 2 post oil pressure sender....it is aftermarket
one is for a gauge, and the other is for a warning light. green (w/ red?) should go to the post that is labeled WK (warning light) G is for gauge) also.. if the sender is on a relocation hose, it needs to have a ground strap on it... (some will not ground thru the hose) |

thanks aaron. i would think that the red one connects to a wire in the tunnel then (i didn't buy my car with a pressure gauge installed... maybe the p.o. was going to, but didn't get around to it). i made a wanna-be 904 gauge so mebbe it'll hook up there!
the sender is mounted on a brass (?) extension and a 90 degree elbow, but i'm sure it was not grounded before. ground from one of the posts? here's a pic |

Hopefully the gauge is correctly calibrated to the sender.

at idle, the gauge showed about 50 lbs, and about 110 or so when revving. how does that sound? ... then it went wacko and is spiked at the top even when the car's off. (IMG:style_emoticons/default/dry.gif) |

Not another one! Group: Benefactors Posts: 4,526 Joined: 1-March 04 From: San Mateo, CA Member No.: 1,743 |
Wrong sender for that gauge. Cold start pressure may hit 60psi. Hot cruise pressure is usually 40-ish psi. 10psi per 1000rpm is the rule of thumb.
There are basically two sender ranges: 80psi and 150psi. Sounds like you have a 150 gauge and an 80 sender, so 60psi looks like 100 on the gauge. |
