Some Wiring
I’ve also done some wiring. The extra wiring needed for the mpg gauge was added, the main +ve wires were cut and moved to the correct place and the other engine wiring was arranged to fit the compact.
Adding MPG wire
The first problem was where to get the pins from as my car’s wiring did not include any extras. Luckily there is part of an e30 wiring loom lying around the garage. This is left over from the donor car which was used in the kit car my brother and I are building (see link in signature). On this loom I found a connector with pins that are 100% correct for the x20 connector (the main engine loom/car loom connector).
Perfect match
To keep the x20 connector protected from water each pin has a rubber seal. I simply cut a hole through the solid rubber seal and pushed the wire through.
There is a metal sleeve that goes with the pin this need to go over the pin before its pushed into place. The MPG pin goes into pin 24 on the x20 connector.
