I am trying to install my fuel pressure gauge and I can't find my wiring diagram. I don't know what happened to it.....

I need to know what color wire gets hooked up to what. . . . Any help would be appreciated!! (It is for a Danin Pricol Optix electric fuel pressure gauge. If I remember right: I'm looking for instructions for hooking up the BLK, RED, WHT and GRY wires. . .)
Thanks,
Dan

Amazing what you can find out just by calling the company!! I got it!

Red - 12V + switched / ignition power
Black - ground
Grey - ground
White - 12V + dash lighting

Oh, and I read somewhere about them closing their doors . . . The man on the phone said it just isn't so! I was glad to hear that and that they will be getting our attention in the future! Good to hear they are doing well. (Why do people have to start stupid rumors that just aren't true?!!)

This brings up another thing: Anyone want to buy an ISSPRO EV2 pyro? Just like new! I'll even help you install it if you need. I like Pricols a lot better and think I just might switch!
