Saves you a lot of time, stop guessing.
Kit comes with multiple plug in Relays. If you need to check if the circuit has power or checking a fan for the AC. Plug it in ,over ride the connection for power directly to what your checking. Great time saver. Who do you know that keeps extra relays around. NOBODY!

Works as it should! I used to jump the fuel pump with the key off on my 4.0L jeep. I had a fuel pressure problem where the regulator would bleed pressure off. This allowed me to hook up a gauge, turn the fuel pump on which should bring it to 29-31 psi and hold it in the rail. The regulator would not, as the o-rings bypassed fuel to return. This relay set helped me figure that out. Sure I could have just used a piece of wire to jump it, but a toggle is nice to have.

I've used these in the field to diagnose electrical issues more than I'd like to admit to. Works every time.
