im wondering where you guys using stand alone 2 bar maps to operate your methanol system got your 5 v from? i have one from the a/c for my drx 90mm harness but im scared that with another 5v tap i might dilute the signal. any other spots that are easy to get to preferebly near the fuse box. but any recomendations are apreciated.

 

I belive there is a 5v reference on the back of you headlight swicth. Pin 13, gray wire. I am really certian about this but check first.

 

anyone else?

 

Tap into the 5V ref. source at the stock MAP sensor at the back of the Manifold.

 

thanks i found it btw. now i need a solid ignition wire that can handle a pull of 15 amps .

 

I just split a suitable circuit in the underhood electrical center with one of these fuse taps/circuit splitters. Don't recall offhand which circuit it was.

 

I assume this is for the pump? You'd probably be better off using a relay triggered with an ignition hot wire so you don't have to worry as much about voltage drops affecting the pump speed/flow.
