Rewiring/replacing switches (1 Viewer)

[Bigegg]

I'm tinkering with the idea of changing the layout/design of my 2000 reg. UK spec 100 series console switches - AC/heater controls, ahc switches, aerial, heated seats, suspension modes, dash dimmer, fog lights, sport/snow mode etc.
Basically all the controls which are not either hardwired into the dashboard or indicator stalks.

Would I be correct in arsuming that they are all standard "analogue" switches and/or variable resistors, and not "smart" switches that send a data signal?

I can't imagine they would be, in the interest of KISS, but just thought I'd check.

One of the reasons is that a previous owner has spilled *something* over the center console, and all the controls are sticky+corroded to a point where even after removing + ultrasonic cleaning they are barely usable, so need replacing anyway.

Confirm with a look in the EWD, but I think all the switches are just contact type. The body ECU, behind the stereo head unit, does all the thinking.

You can use the USDM EWD in the Resources section. It'll be good enough for this exercise.

FWIW, I think most, if not all are still available. Check with Dave Stedman at Japan4x4 to make sure. He can get OEM parts for you at a price which I'd bet is comparable to generic switches and far better quality.

You'll need 89299–60010 Suspension switch, which is a multifunction switch not easily replaced by generic. US dealer stock says discontinued, but I'd bet it's still in production, or at least in a Japan warehouse somewhere. Expect about $80–ish (US) from Dave.

The seat heater switches (84751–60090 [RH]/ 84751–60100 [LH]) are still available at about $40 (US) each, they are rheostats, IIRC.

The transmission select switch, 84720–60120, is a DPDT, rocker (only one side can be engaged at a time, or neither can be), but it too should still be available.
