I need to hook up a relay that only has power when the truck is running. Anyone help finding a specific connection point? I found the fuel pump relay but can't find the wire to it, I also thought about the driving lights but not sure where the wire is. Any help would be greatly appreciated.

I'd say run to a parts store and spend a few bucks to get a test light. Works wonders

What do you need this relay to do?

I think as long as the wire is grounded on the black connector in the power box it will only work when the key is turned forward. But not a 100% on this. Give it a shot.

Thanks for the help, I used the test light and bought a mini add a circuit at Advance Auto Parts and added it to the O2 sensor fuse under the hood so now my accessory only has power when the truck is running. I built a Hydrogen Generator to increase my mileage, If I get good results I'll let you know.

i tried it already and post a DIY on it


its good on the highway but alone its useless around town the rpms run too high for any real improvement + the o2 sensor compensates for the xta o2 w/ more gas

sorry to rain on your parade

 

If you were to add a resistor somewhere on the o2 im sure you could change the sensors by a certain percent. causing it to run with your HOH gas...
