CD player finally crapped out. Ordered AVIC-Z1

[1loudLX]

isnt that the cabin air temp sensor?

AVIC-Z1 wants a few signals for your GPS Nav to work properly. It compares GPS data with Speed, Reverse, and Parking Brake. The first cable harness I connected was the adapter cable I received from Crutchfield. It translates most of the common signals from the Toyota radio connector into easier connections to the Pioneer cables/connectors.

You can see in one of the pics how I already started wiring it together. 12V+ Battery signal and 12V ACC (switched) and 12V Illumination, along with GND all needed to be crimped together. Speaker and Amp outputs were simple RCA jacks already attached to the Crutchfield adapter harness.

Removed the Glove Box. This first picture is not as revealing as I hoped, but shows how I tapped the Reverse and Speed Sense signals at a connector feeding the ECU behind the glove box. They are the pink and purple/white wires that were supplied by Pioneer. You get to the ECU by removing the glove box (2 screws and 2 door stops), and the black plastic ECU cover (3 screws). Change your cabin air filters (if you have them) while you are in the area.

It's the 4th connector down on the ECU. I had read a lot of advice about tapping Reverse from the back-up light harness far away in the taillight housing. I chose instead to tap Reverse signal from the Transmission Position Reverse signal, which I think is an input to the ECU. No harm done so far. YMMV. I referred to the FSM to confirm which wires were which.

The center console trim panel around the shift levers is also held in place entirely by tension clips. The Hi/Lo TCase shift knob just unscrews and comes off. Removing this trim made it easier for me to route the iPod module later into the arm rest storage console. I spent a lot of time cleaning out dirt, dust and gunk under here. Notice the rust? Looks like Wifey might have dumped a drink or two.

I actually DO NOT recommend tapping the P-brake switch signal here, as there is very little accessible P-brake switch wire to work with. I should have tapped the P-brake wire at the cable bundle in the driver's door channel. Or should have removed the driver's seat and caught it coming out from under the console. It was a reddish w/black striped wire I found later in the driver's footwell. In the pic here, I just Grounded it for test purposes. That is NOT recommended for normal operation.

I tapped the reb/blue wire here and the reverse camera only comes on when the vehicle is in park and I press the brake. Must be a brake interlock wire.

Nice job.

After sending you that PM about how to find those signals going into the ECM, I thought the pinout info would be helpful for the thread.

the 2000 FSM shows total of 5 connectors on it. They are all keyed differently with different pin counts, so they should be unique and easy to identify when you are looking at the ECU.

I think this goes from top to bottom, as mounted vertically in the truck...
E5 (31 pins)
E6 (24 pins)
E7 (17 pins)
E8 (28 pins)
E9 (22 pins)

If you could look at these connectors from left to right, then

E8 is the one with the 2 signals I used. Here are the terminal locations when looking at the E8 connector ON THE ECU (not the cable), with the locking tab at the top, and flat surface on the bottom...You'll have to figure out how to match these up mirror image to the actual wiring harness you are tapping.

top row goes pin 9,8,7,(space),6,5,4,3,2,1.
middle row goes pin 19,18,17,16,15,14,13,12,11,10.
bottom row goes pin 28,27,26,25,24,23,(space),22,21,20.

SPD is a V (VIOLET) wire on E8 pin 15. That's middle row, 5th from the left. This should be a pulse from one of the wheels.

R(reverse) is a R-B (RED-BLUE?) wire on E8 pin 2. That's top row, second terminal from the right end.

So if you find the right connector and terminal location on the ECU, look at the wire coming out the back of the connector of the wiring harness that matches up to it for the right color.

Thanks. I'm going to look again. I couldn't find the wire yesterday.

Nice write up and nice deck. I do have a question for anyone that has installed an aftermarket deck. I pulled my factory deck out and I dont see any RCA cables back there. So what am I supposed to plug in to the RCA cables on the harness I bought? Also can someone please post up where I am supposed to tap in to the parking brake wire at. A picture would be even better.

Any help with these issues would be greatly appreciated.
