Hi all

 

Got all the gauges installed am slightly stuck on the wiring, where do I find the wires for Live,common and the two ignition wires?

 

Its a J-Spec TT, my old imori gauges had the live and common in parallel to the light in the glove compartment, but I need ignition wires for the defi's. I dont want to rip out the rest of the dash to get to the actuall ingnition barrell..

 

Any suggestions...how about the wires that power the digital clock? Thats been removed now,theres 4...live,common...dont know what the other two are??

 

p.s anyone know where I can get the T-Piece for the Fuel line for the Fuel Pressure gauge?

Fuses are in drivers footwell. If you have the fuse cover, there will be a diagram on the inside showing the relevant fuses.

 

I was under the impression that the Cig lighter doesnt run on a 10amp fused circuit - making it not suitable for the AEM which requires a 10amp fused circuit.

 

I have a 95 JDM Supra, not sure if the wiring will be different, but the ignition live on the Odometer plug was top left as you look at the plug (pretty sure its a yellow wire - see pic below).

 

You can test using a multimeter or one of those gadgets that lights a bulb when a circuit has power (can't remember the official name for them lol).

 

If your unsure of doing it yourself, get a qualified automotive electrician to wire it all up for you - save your car going up in flames should you get it wrong :)
