i have a greddy boost gauge and profec b....i have all the vacuum lines connected but i dont know how to hook up the electrical...for the gauge...one line is ground, one for 12V power source, one for ignition and one for a light source....for the profec b, one is a ground and one is a 12V power source while the ignition is on. i have the honda manual but i dont understand the wiring diagrams...can some one please help me out..thanks

 

Power? I go to one of the wires entering the car stereo.

 

cig lighter...ghetto..but it does the trick..I think everyone can agree with me..hehe

 

Off the stereo deck is where I got my power.

 

Can you use the same source for the 12 v and the ignition? I'm also confused about this matter. Someone told me to use the cigarrette lighter for the ignition. Now, where do i find a constant 12 v source?

 

I powered mine off the boost controller since its power is hooked up to the ecu.

 

anyone else have any insight?? Where do i find a constant 12 v source... and what the hells the point of it?

 

crusie control red and white wires

 

off the fuse box...spice in w/ the "acc" FUSE.

 

cruise control is the best place especially on a civic since it's right near the pillar

 

do you have a stock stereo or do you have an aftermarket one?

 

pull out your owners manual. just plug it into a fuse in the fuse box. for light source, wire it into the fuse for "instrument lights". for ignition, plug the wire into the radio fuse. use the radio fuse for 12v too. its really simple.

 

There should be plugs near the fuse box that have spades sticking out of them. All you need is a test light to find out which one is 12v constant, 12v ignition? there is like 5 of slots there and u can just get a female spade and plug it there. Hope you understand what i mean. Paul

 

OK this is what you need to do. Go buy a test light (really cheap). Connect the ground wire of the test light to the body of the car. Then with the key turned off start probing wiring with the test light until the test light turns on. That will be your constant 12v. Connect that to your 12v power source wire. Then with the key turned on start probing wires until the light comes on again. Now to make sure that this isnt a constant 12v turn the key of and make sure the light turns off. If so this will be connected to the ignition wire. OK? got it so far? Now for the light source turn your parking lights on and then start probing again until the light comes on. Again to make sure this isnt a constant 12v turn the lights off and make sure the test light turns off. This will be connected to your light source wire.
Hope this makes sense. Good luck.

EDIT: And oh yeah your ground wire connect to the body of the car somewhere.
