Z20/1JZ A/T dash wiring

[mini_me1209]

In the process of wiring up my digi dash and modifying an older jza70--> ma71 dash wiring chart to benefit z20 owners. Basically, I need help modifying the ma70 side of the chart/diagram to z20 dash wiring. In this particular case, im interested in modifying the chart for an 89 mz21 with A/T and a digi dash. Any help would be greatly appreciated!!

Hey mate, have you got any further on this? do you know where the a/t wires go? and do you know how the speedo connects up, as the mz20 electric speedo and the jza70 has a analoge speedo.

Im am waiting on my jza70 IG1 harness to arrive and then i will comense the wiring mayhem. From what i've pieced together, the wiring is actually very straight forward! 95% of the wiring(colors) between jza70 and z20's are the same or very similar. the main diagram I am using is inthe original post. I plan to modify the diagram to be consistant with an a/t z2x soarer. I havent looked to far into the speedo situation, but i do believe a A/T speedo sensor is required. I will keep this post updated!
