Hey guys had anyone had problems putting a coupe dash into a sedan I've just changed mine and nothing's working indicators oil lights the plug went In fine do I'm confused

That's because the wiring is different. You need to
rearrange the wires (pins) in the plug. Theres a wiring
diagram on this site somewhere that shows you how

i guy on here has a website. i think its called www.shoeys.com and go to the wiring page.

Cheers guys ill see what I can do with the diagram

found it

What if you have the coupe dash loom too? Is,it just a,matter of plug in coupe dash loom to the plug near Bonnet release and your done?

Also with elec ignition, how,to wire in the stock tacho?

Yes, I would expect that a coupe round-gauge loom will plug into the main harness just the same as a square-guage loom and allow you to use the coupe dash unmodified.

Also I would guess no problems with electronic ignition. 1970-1973 1200 tachometers are coil-loop induction type so should work OK.
