My 78 FJ-40 has an interesting starting issue, when the key is turned over, it starts on accessory as well as start. You have to be careful when you turn the thing off because the starter will sometimes engage right as you flip the switch off.
I first though the switch could be defective; then after thinking about it for a while I thinking it could be a wiring issue from a PO handy work. The starter has a heavy gauge wire (black with white or yellow stripe I believe) connected to it via a spade connector.
I got this truck in pieces and used a wiring diagram to hook most everything up; so far everything works as far as gauges (as if they are really that accurate!) as stuff.
Two other problems I've been having and can't seem to figure out, taillights and turn signals. I've wired up some LED turn signals and brake lights, they are the typical slip in trucker type. The brake and taillight works bu the turn does not. I do think I have a bulb up front (turn signal) that is out, that might be why the turn signals aren't coming on. Need to check the blinker relay. Is the relay a Toyota only item? It looks pretty big and I seem to recall that the Toyota turn signal system is not GM compatible. Easy way to test this unit?
Thanks for your help and input!! -Junker
I was also concerned that the LED lamps might not have enough load to run the blinker, I have had this problem on motorcycles and had to add some resistance to the circuit.
Biggest concern... back up lights. I have several connections along the frame that could be backup-light circuits and or 4th gear sensor wires, there are a total of 4 single female (eh, eh) sockets, they are blue and blue with a red stripe I believe. I can NOT find this stuff on my wiring diagram. I need a bit of help here.
There is also a single heavy gauge black wire coming from the same harness with a male spade (Toyota type with the clip) connector on the end. I can find no receptacle for this wire. I thought it might be an E-brake wire but that stuff is under the dash hooked up above the pull leveler, right?
