Hi



Ok so on my 87 t2 i am installing an aftermarket gauges and a thermofan from sumit racing but i need to tap into a ignition wire so when i put my key into the ignition it turns on so i was wondering what wire is it that i need to tap into dose anyone know. thanks

 

i usually use one of the radio ones, i'm not sure which whire it is, i just use the voltmeter.

 

Is this thermofan being used inside the car or are you talking about a e-fan for the rad?

 

I am guessing you talking about triggering a relay to turn on the e-fan. I hope you not trying to run the e-fan off of a regular 12v source.





If your triggering a relay a test light is your friend, there are a few wires in the front of the car that will support the voltage of an e-fen, remember they draw a lot of current, I burned up my relay up line with the current I was pulling on my e-fan.



There is already some wires for the AC e-fan but I suggest you pull from the altenator to a relay then have a 12v source switch it on. Any radioshack can help you with a wiring scheme.



Good luck and do not burn your car down!!
