Westach FP Gauge wiring

[wcoomes]

Finally getting my Westach Fuel Pressure Gauge connected, but my pins aren't at A,B,C & D as shown on the Westach wiring diagram, the pins are at 2,4,5. Any one have any idea how I'm supposed to wire this thing?

Here are the links to wireing for all their gauges: http://www.frostalarm.com/hookup/

My gauge had both letters and numbers on the back. Hard to read.

I've been to that page, my gauge is a 2C8-37, I see only a 2C8-36 on that page.

The wiring diagrams are by series. If you look at them you will see that the only difference between gauges is the type of transducer used. The one I bought is a 40 PSI gauge. It is not listed at all. I inquired about a gauge like the others listed that showed 40 PSI instead of 30 or 60. They said no problem. I think all of the gauges with the same first three letters are wired the same. Check a few of them to make sure.

I called Westach, since I have no pins @ A,B,C, or D, they said #5 was the ground, #4 was positive, #2 receives one wire from the sending unit, and the other wire from the sending unit should be connected to the same ground as #5.

Just use an A/C charging connection at the V44 test port with your other end hooked up to your F/P sending unit. Should work perfectly.
