Picked this up a while back, might be obvious to some.

And if you have a pre-1992, it might be over next to the battery.

Very cool, thanks for sharing this.

This is actually a good trick to have in one's bag of tricks ;)

87 yj 2.5 tbi is stalling once hot and not starting when it is warm. Fuel pump relay clicks but no pump when this happens. Do you think this will help?
 
this will jump the relay and supply power to the pump constantly. Its more of a troubleshooting method rather than a solution. if jumping the relay causes the pump to run correctly then your relay could be a cause, or something forward of that.
 
Can say that all of the relays on my '95 YJ are the same foot pattern....So if I think ones gone bad, I just toot the horn and if it works,
Just swap them over to see if there are any problems....
