Wiring loom

Hi to all,
I have a 1979 Santana with a series 3 engine in it, how difficult is it to change the front bulk head wiring loom. Ihave brought one from auto sparks but I have never done this before so any help would be very welcome
Cheers martin

Series landys wiring gets butchered a lot, so, nothing is as original, if a new loom will work is a big question, i'd rather strip and start from scratch with building a new loom rather than trying to fit one which was from an original vehicle...

If you know how to use a multimeter you may be ok, but, good luck!

If you have bought a new one there will be no problems, just install following the old one. Maybe some added switches need to be removed or new wired but as said if you know to use a multimeter no problems.

I'm doing a new wiring loom on my Santana 6cylinders and with time it's not difficult:

Thanks will have ago.did you take out the old loom first?or lay the new one over!
