I hope I don't get too confused with all the extra lights & gauges compared to mine 

 

"honestly officer, I was looking at this gauge here, I thought that was the speed I was going.  And that light there, goes red if I go over the speed limit.  honestly it hadn't gone red....... ".   lol 




(Reads boost gauge) - I was only doing 40 (psi)

I completed the installation of a Solid State Relay to replace the original Power Steering Relay. I also installed the Ecliptech Shift-P2 progressive shift light just in time for the MR2 Wakefield Park Challenge next week. I'm very happy with how they both turned out.
 
This is the solid state relay that I used to replace the power steering relay. It's the 'SY4086' 100 Amp one from Jaycar. The original PS relay has a thick black wire and thick white wire (for the load side) and a thin black wire and thin white wire (for the input side). The thick wires already have ring terminals which can be unscrewed from the original relay and screwed straight onto the solid state relay. The thin wires need to be cut from the original relay so you can crimp on new ring or spade terminals to suit the solid state relay. As you can hopefully see in the photo, the pinout for the solid state relay is as follows:
- Thick white wire = output +
- Thick black wire = output -
- Thin white wire = input +
- Thin black wire = input -

 
This one shows where I mounted it to an existing metal plate (which can act as a heat sink) next to the fuse box in the frunk. Some SW20s seem to have some sort of ECU mounted in that spot, but not mine. Ignore the other 'regular' relay nearby in the photo with the red wires, because that's for the electric pump in my air-to-water intercooler system.

 
These photos of the Ecliptech Shift-P2 aren't very good but they'll have to do for now. This one shows how nicely it fits above the steering column without obstructing the view of the gauge cluster. The slight curve on the bottom of the unit matches nicely with the curve on top of the steering column plastic, and the the curve on top of the unit matches nicely with the stuff behind it. It looks like it's meant to be there!

 

 
I made a hole in the plastic above the steering column, just behind the shift light, so the wires could be hidden away. 

you're right, that looks perfect. It's like it was made for sw20 owners!

Thanks for sharing the info on the ps relay. Certainly provides a 'once and for all' solution to an increasingly common problem.

That is pretty cool, repurposing an xc Falcon column shift like that!
 

 

Just a small update, regarding my tail lights and brake lights.
 
The previous owner of my car swapped the later model 'kouki' rear lights onto the car, but when my headlights are on it only illuminates the outer red tail lights, and the brake pedal only illuminates the inner red tail lights. This is the same on many SW20s, and I was never bothered by this until I was on the last MR2 Club run up to the Blue Mountains, following Eddie in his immaculate SW20, and I realised that his tail lights look so much better when both the inner and outer tail lights are doing the same thing.
 
I was going through my garage today and I remembered that the previous owner of my car gave me a bunch of random stuff all those years ago, but I never looked closely at some of the things that he gave me. Well, it turns out that he gave me 4x dual filament bulbs and matching bases. Score!  Now I don't need to buy anything and I just need to connect the extra wires for the dual filaments vs single filaments.

No idea why they weren't like this from factory.

This was one of the very first things I did to mine when I first bought it, they look much better when wired for all four lights doing the same thing.

Guess they just thought the Gen 1 lights look better wired this way. 
 
I have all the stuff to do it at home but the soldering iron is the bane of my existence haha. Maybe this is the month I'll get the globes installed :p 

All done
