Here you go
All the ignition wiring is on the left between the battery and the firewall and brake booster. The motor is definetely a 4ZE1. The unknown vacuum switch is under the red ht coil lead. Yes geeves (he who notices everything) the airfilter wingnut is missing -will replace tomorrow.
and the power steering bracket is not original this ute didnt have powersteer when I bought it
and the unit I bought came out of a deisel so belt set up was different and it didnt have a idler pulley with it.
