so I just found out a bad thing if you own a pre-update

the heater/aircon fan circuit pulls full current thru the ignition switch, wiring, fan switch etc..NO relay/s

lots of ways for things to self-immolate, including the ignition switch

I found a corroded connector at the resistor block had fried the wiring & connector..now fixed..but the original design flaw persists (corrected on post-update, used relay and switched -ve)

There is one obvious solution, which I will probably implement

Make a 4 relay pack ($17.95 on Ebay), mount adjacent to fan, run wires thru firewall

one of my '96 has a aftermarket ignition system fitted, old one must have burned out, and taken some wiring with it,
