I just bought 4 gauges from prosport: mech boost, water temp, oil temp, oil press. I got then power, but can't figure out how to get them to turn white during the day, amber at night.

Wires are as follows:

Red - accessory power
Black - ground
White - accessory power
Orange - head light switch
Green - sensors

I connected the red with a spade connector I to the empty port on the inside fuse box. Black to ground. White to sunroof fuse. Orange to head fuse. This way, it only glows amber. On their website, they say white to acc, orange to head light switch for white/amber and that's what I thought I did. Are there better places to connect the orange and white wires? Are mine incorrect?

Also, I wired all 4 gauges with one wire per color. Three turn on at once, one turns on after the other three. What could be the possible reasons?

Thanks!

connect the orange to your ash tray light power feed.

the headlight fuse gets constant power so it will never switch over.

it's also probably a good idea to tie the red and whites together, because prosport is ignorant of how to build real gauges(oops, that sounded biased. the power feed is redundant and they are very sensitive to ground and source voltage issues).

 

I really don't want to tap into my ash try wires. I read that grounding the dimmer can lead to major problems potentially. Any other place I can run the orange? Tail fuse? By tie together the red and white you mean run them to the same power source?

 

the only other place you can tie into is your parking light circuit. which color wire that is off the fuse box i don't have on hand at the moment, someone else could jump in with that or with a little searching you should come up with the location and color wire needed.

i really doubt it will damage the dimmer circuit. it is in essence a low amp sense wire and not actually powering your gauge lights, just using the switch in voltage to tell them to turn amber instead of white. they are wired the way i described on my RX8 and i haven't noticed any issue.

 

Ok thanks. What did you mean by two the red and white together?

 

I ran 4 Defi gauge's dimmer function from my little ash tray power wire. If the gauge is built correctly, there is no load. It is simply sensed voltage. I can not speak for ProSports.

 

Do you know what wire I need to connect to? I'm running one wire for all 4 gauges down into the ashtray if I do this, and there are two sets of two wires: 2 red with blue horizontal strips, and 2 red w a green vertical strip. Would I just twist those 2 together as connect it to the orange one?
