Project hopeful, no will power

sounds like its been apart before and not been put back in the right place, the only two plugs I know of like that on a 306 are on the chassis leg in front of the gearbox.

unless a late 306 with a hdi is different.

whatever its for, just pull the engine out with the loom still on it, you can buzz from the plug back to all the sensors etc on the engine quite easy then.
