Hi, Got a few electric probs with my 1990 Town Ace Super Saloon (Import) Auto, 2L Turbo Diesel, this is the hi-(Skylight) roof with all the fruit. Eg:- Electronic anti-dive front end. Electric Blind set Twin A/C 6 Seater (Rotating Middle Row) And all the other electric stuff, mirrors, windows, doors etc. etc. Twin battery system with a 5k Watt inverter, to charge my Wheelchair/Scooter on the move. This system is fitted with a h/d isolating solenoid to ensure it only works with ignition on. So there's this gremlin what we cant find, primarily it seems to involve the 6 speaker standard system. I am fitting a 2Din Stereo head with b/t, gps, radio, cd/dvd, so to interpret the Toyota wiring colour codes I need the wiring diagram, to ensure that I don't explode my $250 Head unit. ( Yes I know it's probably worth more than my truck :-)). A pdf copy of the relevant manual pages would be most helpful, or web info as well. Thanks in advance. Adrian
