Hello mates, have you still got the pinouts for the jzs171? I´m getting crazy with the wiring to my 1jz S14a.

To wich pins I need to get power and grounds? for what i read until this moment, i know the wires need to get power, BATT, +b, +b1, MREL, IGSW (this one it is when the ignition its in the position to crank right?), +BM (for the ETCS-I?), and EC (for ground right?)

So much aprecciated and thankful all the help.

Cheers

I need some help. Cant get my is200 A/C ECU to talk to the JZS171 ECU # 89661-3A870. So my A/C will not run and outside temp shows E.

hey, is this pinout still available? i also have a JZS171 Crown motorset that am trying to get running in a 67 mustang. i could use the pinout. could someone just post it here?

thanks so much for the email @hititup. trying to figure out the wiring now. which pins exactly need to be grounded, and which ones need to be fed with switched +12v and constant +12v battery power to run? ive been looking at some jzx100 wiring but i there are some inconsistencies that i'm unsure of.

what exactly are you working on JZX100 or JZS171? its 2 difference wiring.

its a jzs171 harness and computer. im aware that they're different pinouts, but looking at the diagrams for the jzx100 and jzs171 i figured i could still find wires like MREL, BATT, IGSW and B+, etc. im assuming i can follow some of the wiring guides to get the engine to simply fire up eg; even if they're not for a jzs171 specifically, won't the wires that need to be grounded and fed +12 be the same, just in different locations in the pinout?

this is the writeup i was referring to.

I may be in the same boat as u, almost everything in my is300 is functional running on the jzs171 ecu, but for the life of me I can't figure out why my A/C isn't working.. I have run out of ideas.. the ac button inside the car does not engage the ac clutch, but light comes on as normal.. just outside temp air blows.. I have replaced and rechecked many parts of the ac system with no luck.. I have narrowed it down to literally electrical.. but still no luck.. I bridged the ac comp relay and the clutch turns on but even then, no cold air comes out the vents.. pressure on the ac manifold gauges show high on the low side and low on the high side.. so it is not circulating..

have u found a solution?
