@shackleton:
I've got some sort of the same problem, bought a set of aftermarket gauges (oil pressure&temp) for my '86 carb. V8 but haven't got a clue where to put them... (the sender units that is).
You managed to put them installed? Where did you put them? Got any pictures..? I've got the original sender for the dashboard warning light in place in the engine bay, but need place for both temperature and pressure sender units, are there any 'free' outputs I can use?
Thanx...
