Hicas swap

[Silvia180SX]

I have my 1991 Hicas rear suspension intact from my crashed 240. I'm going to try to put it under my 89 body that already has the 91 drivetrain in it. The lines are straightforward but what about the electronics? The wiring from the rear suspension just seems to get lost in the harness. I don't need the entire rear compartment harness just to have Hicas do I?

Most likely you do... The HICAS wiring is pretty different.

My advice would be to grab the VLSD, driveshaft, and sway bars from your '91 and install them into your '90 without HICAS. You won't notice the difference.
