ok, so here are some pictures from my install.
Materials:
-30A SPST Relay
-Female Quick Connects
-Ring Terminals for Ground and Power
-Quick Splice
-Wire Loom
-Zip Ties
Tools:
-Drill
-Dremel
-Various Dremel Bits
-Hole Cutters
-Wire Cutters
-Wire Strippers
-Pliers
So I decided to go with a relay instead of just going off the purple/black wire. Not saying the purple/black wire is bad, I just decided to make sure and not have to worry about it.
I ran a wire off the positive terminal on the battery.
Ran it under the battery following the other wiring. Under the fuse box, up under the intake port, under the wiring on the driver side fender, to the carpet along the firewall, through a grommet in the firewall.
(if you look on the firewall, look for the round indent in the carpet, thats about where the grommet is. close to the nut/washer that holds the carpet up.)
Overall, the wire isn't very noticeable and doesn't look bad.
From there I ran the wire through the black rectangle of material found in the cowl. This lead the wire into the under-dash area near the clutch pedal. (sorry, no pictures as I already had the cowl back on)
I routed the wire out of the way and over to the right side where I mounted the relay.
a closer look
you'll notice the fuse holders for the seat heaters zip-tied out of the way but still accessible if need be.
This is all located right behind the driver side lower knee panel so it's all easy to access.
I then tapped into the purple/black wire with a quick splice and ran that wire up to the constant power wire and followed the same path.
Here you can see the main seat heater harness where it runs along the center of the car and where it comes out for the seats.
You'll also notice the wire loom, that holds the power and ground wires for both seat heaters.
Here is the under side of the center console where I brought the switch wiring through.
you can sorta see how I cut the tubes to allow the wires to pass through.
And here is where I mounted the switches.
it's a little further back than I would like while you are sitting in the seat but it's not bad. Not like I will be looking while I'm driving or anything. Plus it keeps the switches out of the way in a place that will never get used anyway.
I haven't tried the seat heaters yet. I just started the car for the first time in 4 months yesterday and it sounds good so far. I let it idle for almost an hour. I flipped the switches to make sure they were working and they were. Will test the heaters out on the test drive of the car. I have to top off the coolant, top off the oil, add and bleed the PS lines, put the fender liners on, put the bumper back on, put the headlights and grill on, put the bottom bumper cover on and then the wheels. Then I can drop it off the stands and take it out for a test drive and see how everything feels and hope all goes smoothly.
