MG MGB GT V8 Factory Originals Technical - V8 Wiring Harness

Hello again
I am replacing the wiring loom in my 1970 B which is also getting a V8. It is a chrome bumper obviously and I was wondering if it is worth the extra 15 pounds to get a V8 chrome bumper harness from the B hive? ie will this harness go in easily as if the car had been a factory V8?
TIA

Stainzy,
I think you will have more trouble adapting a V-8 spec harness to a 1970 car than you will with making the few modifications to the 1970 harness for the V-8 engine. The biggest changes are lengthening the distributor, coil and alternator wires (a small task) and putting in an electric fan circuit and relay (a slightly bigger task).

The 1973/4 V-8 had rocker switches on the dash, and their placement was somewhat different than the switches on the 1970 UK-spec cars. In addition, if you are doing a roadster (you didn't specify), the V-8 harness would have some superfluous connections, like the heated rear window and rear courtesy light.

I would buy a 1970 harness and modify it to suit the engine and fans.

Cheers,

Stainzy,
Paul has a point. Two other potential problem areas -the Factory V8 had the wiper and overdrive switches are on a stalk on the steering column, and also the rev counter connections will probably be different to your '70 B.
Hope this helps

Thanks guys,
You're absolutely right of course (and it is a roadster by the way). I'll just go and buy the original for the 1970 4 cylinder and modify it. Thanks again,
