Hi all

I'm useing a modified Escort MK2 loom and utilising the redundant HRW wire to power my fuel pump. Been having random fuel shortage breakdowns . trying to engage brain cells on this and wondered if there was a timer or overheat cut off incorporated into the relay/switch/inline device . to cut the power and save the battery , like in most modern cars . could solve my problem if there is ...any thoughts greatly apreciated . will listen to see if my pump is going next time I break down

I removed that circuit from my loom. There is some for of relay that operates the HRW. I think it has a fuse on the relay too. No idea if it is timed though.
I ran a new cable from a relay controlled by the new ECU.

I used the HRW relay for my fog light - powered from the lights , so the fog light can only be switched on with the lights on . There is definatly no timer on mine .
