Unless you are good with electrics you will end to have your loom professionally adapted. Sorry if you know this but if that is your question?
Yeah, I'm good with all aspects. I'm happy to mate the two looms together. Just looking for guidance on any issues that people have experienced I.e. wire X for component x needs a x ohm resistor fiting. I'm happy to have it done by someone who has the experince. When I compare the cost of getting it done by someone else to the time it's going to take me to do it on my kitchen floor and inbetween work etc. It's looking like paying someone to do it, is the better option.
