Tony, email me, I have just gone through all this with Micks car, rewired the engine bay back to original, I'll email you some pics back.

I am just up to fixing all the years of bodgie wiring.

What was the original setup for the Battery to Body grounding in an LX V8? It goes from the neg terminal to a bolt in the rad suport panel just in front of the battery

I have all the original wiring for the engine bay but this connection eludes me.

Also what was the connection for the anti-diesel solenoid for the Rochester? The car had a Holley on it so the engine wiring loom has been hacked up. Oh joy, i can help with the wiring here, you'll need pics

I can fix the loom good as new but the tacho wire is joined to a dark blue wire that does not go back to the main connectors. It just resurfaces along the loom and appears to be for the anti-diesel solenoid. Tony, can you send me some pics of what you have there

I have identified all of the other connections as per standard LX/LH.
The engine loom has 6 connections on one plug and 2 on another.

Plug 1 -6 wires
Power to fuses box -Red
Ignition �Yellow
Alternator - Can�t remember-Brown? yes
Starter solenoid-Purple
Temp-Green
Oil Pressure- Blue

Plug 2 -2 wires
Tacho light pink
Coil resistor (yellow wire) bypass wire-Brown.

And then the A9X cooling fan control circuit for the relay came of the ignition circuit too. it comes from the alternator and goes to the anti diesoling solinoid. it's hard to explain without pics

Lots of fun;)

maybe this helps?

The original battery to body earth wiring was barely marginal, even when in perfect condition. It was a thin black wire straight from the battery -ve terminal to a bolt on the radiator support panel.

I can help you out with a custom made heavy duty earth cable if you want. If originality isn't a problem, I'd probably go from the battery -ve to one of the larger front bumper support mounting bolts instead of the rad support panel.

Hi Guys.

From memory, the pink is ignition +ve supply (to carby solenoid etc).

The tacho signal wire (from -ve coil terminal) is brown, as is the alternator light wire (these 2 are easy to mix up).

The yellow wire is the only one that goes to the coil +ve. The ballast by-pass is done inside the harness between the ignition switch & the engine harness plug (where the yellow & dull pink join).
