So after a few days and endless nights I've had a neighbor round that restores cars and luckily used to own a auto electrical business and the bad news was to start again with the whole front end wrong cables in places cbs mod in a bad location and he can't figure out the extra fuse box and relay box so there out and I've started all over again with the front end but I no now I'm on the right track. Only 2 issues the VW polo heater as no cables so need to figure out the right connections on them to go to the right connections on the switch and the wiper motor which as 5 cables and I've to figure out which is which but by the looks I'm guessing it's a kit and not from a sierra so trial and error process with this. If a home as a aftermarket wiper motor kit and no the wiring is love to hear there's 6 cables. Green and red, red and green , green and brown, black and solid red.
