Hello all, ive recently built a citroen AX with the running gear of a 03 vtr 1.6 8v with a bosh 3 pin ecu, my problem is i cant get a rev counter to work ive tried putting it on all 4 of the feeds off the coil it works but its lazy, does anyone know what wire it needs to go on, on the ecu, iam guessing it must have a signal wire, its a 3 pin bosh ecu, i know that the rev counter normally goes on a wire that is on the diagnostic socket but i only use the engine loom so iam a tad stuck, also does anyone have a 03 wiring diagram for just the engine loom, many thanks jon
