Hi, I've bought a project 90 4C with the engine already removed, it came with a disco 300tdi to put in it (with the back plate already modified to fit the LT77)
It was missing the engine harness so I've bought one off ebay, I also bought a glow plug relay (with wires attached) from ebay too. That's what's puzzling me. I've found this helpful diagram.
My 3 is red/brown not white/red and my 4 is black instead of white.
In the 90 I have 4 leads near where the relay should be mounted, I've identified the thick 12v from the battery but the others are puzzling me as the colours don't match the relay ones, I've got.
A set of three with round connectors Brown Black Green
A set of two with square connectors Yellow/Black Black
A set with square with a cross connectors Green/ Black Black
Any ideas? Any help greatly appreciated. Thanks.
