Wow thanks guys for the warm welcome much appreciated, sorry for the late reply I’m working nights at the moment.
So I have a bit of it worked out using the diagram. Engine loom is now in place and connected, the main harness is sitting in situ, but a couple of bits I can’t work out even with the diagram.... unfortunately not having the old one to compare too is taking its toll.
Off the main harness in the engine bay, I have the rear harness worked out, (but is it worth the hassle of getting it through the chassis?), I know which is the glow plug timer relay, as stated the engine loom is connected. That leaves me with;
1 block of four connections which has, 1 brown wire, 1 white wire, 1 white and black and 1 green wire to it.
1 block of five connections which has 1 white and orange, 1 purple and orange, 1 green, 1 white and 1 black
Then there is 2 black and white with male and female connectors, I’m thinking they go to the brake fluid
1 white and orange with a female connector.
Obviously the lights, horn, heater etc, I’ve worked out.
Blimey that’s a big list for now but any help at all will be most appreciated!!
Many thanks
Tom
