Hi all ive finally bit the bullet and got me sen a stand alone ecu the mtech v4, ive wired the loom into my RWD escort, the only wire im struggling with is from pin 11 on the ecu to the fuel pump relay, the diagram dosent show what it connects to. all the rest of the wiring is fitted and tested. mtech arent open sunday, so i cant ask them until then.

 

If the ecu outputs a negative down this wire then terminal 85 of the relay, if it outputs a live down this wire then terminal 86.
Relay is wired,
85 = earth
86 = live
87 = output(live from 30 once "on")
It doesn't matter which way around 85 and 86 are so long as one is earth and the other live.

30 = input from battery via fuse, live input
