I was wondering if anyone could help me figure out how to wire my gauges. I currently have a PLX dm-100 /wideband gauge hooked up on a toggle switch. I would like to rewire it along with my new autobmeter boost/vaccume (mechanical ) and autometer 100 psi fuel pressure gauge (electrical) gauge so that all 3 will come on when the trucks turned on. Im currently without a computer so its hard for me to search. I just dont wanto get into cutting and splicing and mess something up. Thanks for the help guys.

 

So my idea is this.... black wire to battery ground.... white wire to a wire in the dimmer harness for the dash lights. Then try and find a wire off the cigerett lighter for the red wire?

 

Ground wire is fine, but the cig hot wire is always on, so your gauges would be on even with the truck off. Go to autozone and get an "add-a-circuit" and use it in the front fuse panel for something that has power when the key is turned but not when off. This is what I did and I used the instrument panel slot I think.

 

Do you by chance have a picture or know whay fuse yoy tapped into? Is it ok to run all 3the gauges off the same one? Btw thanks for the help man i really appricate it.

 

Its the top right one in the inside fuse panel I think. Yea I have like 6 things off of the same one.

 

Ok cool in the morning ill check it out and see what one it is. And good to know. What amp fuse are you running in there

 

10a i think

 

Ok cool. Ill see about gerting one of those from.vatozone. as far as hooking it up tonthe dimmer harness ypu by chance lnoe what color wire ill need to tap into?

 

you could relay the red wire off the ignition switch and the white wire off of the dimmer.if you shoot me a pm with your email address i can send u a wiring diagram for your truck

 

Well i got it hooked up. Neg/battery. Power from the fuse box top right 10ampon fuse. And the ilumanation wire to the brown/white stripe wore in the dimmer harness
