Wiring up a 10amp line for my methanol pump, it requires a 12v ignition switching source, but im not sure where I should tap from to be honest. Has anyone ever dealt with this before? Where do you tap the easiest point for 12v ignition? I was kinda hoping i could have used a constant 12v for the relay because it has the extra tapping point right on the battery terminal but it says to use the ignition source.

 

Theres an extra spot in your fusebox under the dash that you can run a 12v constant source too.

 

like he said there are spots for different 12v sources

constant and accessory,

get a multi meter and with the car off look for the one giving 12v's out and thats the constant

turn the key to the on position but not to crank it and look for the others that give 12v other than the constant ones.

use a female connector to plug into the fuse box.


I've wired my radiator fan, remote start, and fog lights. safest and most professional looking way to do it.

 

Or search and find a etm(electrical troubleshooting manual) pretty factory and use that. There are a few online.

 

what exactly fuses those option ports, because only the 12v constant, parking lights, and 1 ignition 12v work, the other two are dead, and i already have the other ignition 12v used for my fog lights

 

Move the fog lights to the park light free pin and use the 2nd ign. free pin for the pump. 94

 

nevermind, figured it out, #17 powers the second 12v constant and #16 powers the ignition 12v next to it, apparently they are blank fuse locations that need to be filled in to power those options.
