First of all i am a long time visitor and i have finally joined up, I find this site very informative.
I am looking for the correct wiring procedure for an Impco system on a 4 litre EL if possible.
I did find a post but am not sure if that is what i need or not. also I was unable to print the wiring diagram or save it.
thanks, Dave.

Good luck finding the diagram. I am after one as well for an Impco 225 that is on a DC LTD. If you happen to get your hands on one send it my way as well! I will do likewise. Cheers and good luck!
