KLF,
Thanks, but I already have those drawings printed out. There does seem to be some inconsistency in these write-ups and none of them have absolutely answered my questions. Also, there is not a functional description with the TRD elocker drawings like there is with the FZJ80 elocker drawings. That link is a great resource however.
My plan is to take 2 TRD elockers with the factory harness, cut off the 8 conductor connectors and run 6 conductor wire to the FZJ80 ECU from each elocker. Ideally, I would like to know exactly how to connect the wires before I start. Therefore, I need to match the FZJ80 ECU pinouts to the TRD elocker pinouts. Most of the wires are obvious (e.g. ground, Lock position switch) but some aren't. For example, there are 2 motor wires, (light green/red and light green). I think power on to lock is green and power on to unlock is green/red but I can't be sure. I have a similiar problem with the 2 limit switch wires (light green/black and light green/yellow).
Unless I get confirmation otherwise from someone, I have concluded the following. If you look at the rear elocker on the FZJ80 elocker wiring diagram (link is in post 29), you will see 4 wires (2 for motor power and 2 for the motor limit switch) with wire colors labeled G-L, G, G-B and G-Y. If you then compare these colors with the wiring for the TRD elocker (link is in post 39, BTW they are from the same website which is a fantastic resource!), you find the wire colors as LG-R, LG, LG-B and LG-Y. Not surprising that they aren't exactly the same as they are two different elockers. I have decided, in the absense of any further information, that functionally the wires should match as follows:
FZJ80 wire color .................
TRD wire color
G-L ..........................................LG-R .................(Motor power)
G .............................................LG ....................(Motor power)
G-B ..........................................LG-B .................(Motor limit switch)
G-Y ..........................................LG-Y .................(Motor limit switch)
I have no evidence other than "gut feel" that the two motor wires and the two limit switch wires would wire up this way. One or both could be backwards.
If I have some kind of confirmation on this one question, then there would be no guessing when I start wiring. I have everything else figured out.
If I can figure the rear elocker out, then the front elocker won't be a problem connecting to the FZJ80 elocker ECU as the front and rear elockers shown on that diagram are depicted exactly the same.
BTW, KLF, the link that you gave me in post 8 is excellent. Here is the link again:
Outdoor Recreation Network - Off-Highway, Jeep, & 4x4 Fun
This write-up gives an excellent explanation of the 8 pin factory TRD elocker harness with a pinout diagram and explains how to go from the 8 pin factory connector to 6 conductor wire to the ECU (1 pin isn't used and 2 grounds are rationalized into 1 conductor).
I think there is a mistake on the pinout table, however. I'm pretty sure that Pin 7, shown on the table as Green-Black, is actually Green-Red. In fact, the narrative under "Analyzing the Wiring" refers to the motor power wires as Green and Green with a Red stripe. FWIW.
If anyone has actually managed to read this far, apologies for my obsession with the detail on this wiring. I live in England most of the year and I will only have a couple of days to do this entire modification when we fly home this summer. I don't want to be trying to figure out wiring on the fly if I can help it. Also, I don't want to risk damaging 2 new TRD elockers because I have the wiring wrong. Assuming that I can get this to work, then I will write it up as idiot-proof as possible so that anyone that wants to make this mod with an FZJ80 elocker ECU and/or FZJ80 elocker switch can do so easily.
