Thanks a lot to all, for sharing your experience. I probably am going to install Westach gauges then, it looks I can get a lot for the money at Geno's, and I think I'll go with the A-pillar 3pc. . I hope I do not need to install a special fuse(es) or one of those painless wiring harness for that. Did you guys use anything extra like those, or just straight hook up. Thanks again. Ilian
I just installed Westachs in a dual A pillar pod. FP and combo boost/EGT.
You need a source of switched 12V (i. e. hot when ignition is "on"). If you want the gauge lights to dim with the instrument panel dimmer, you'll need to tap into that circuit, as well. Geno's includes a couple of taps with their gauge kits. You can also use one of those "painless" wiring harnesses, or something else that piggybacks onto the fuse panel. Or, you can hunt around for a switched 12V source that's more of a "direct" hook up - though you'll probably still want to fuse it.
I opted to leave the gauge lights on full brightness all the time, so I only needed one power supply. I already had an auxiliary electrical box attached to the top of the PDC (containing relay, fuses, terminals, and a few unused switched 12V sources), so I didn't have to tap into anything at the fuse panel. If I was starting from scratch, I'd probably add this box first then wire everything up just as I did. I like having the easily-accessible switched, unswitched, and individually-fused power sources available.
If you go with the Westachs, those that have the little lamp inserts with red or green "caps" to color the light, be careful inserting and removing them. I used the green caps, installed them, then pulled the insert back out of the FP gauge housing. The green cap came off and is now trapped inside the gauge. I'm in the process of replacing those bulbs with LEDs.
