I don't see where the Throttle Control is fed by the SL relay. The schematic does not show the wires as connected to each other, merely passing by. A black dot indicates a connection. They both receive power from the same wire, but that is before the fuses....

Dai is driving his car home as we speak his was the first to have this mod done on,I called him and ask if everything was OK he said everything is like normal.

Whee! and friends, GaleForce is correct. The "COIL" does receive power through CB#48.
The Throttle Motor Control Relay as a whole does not receive its sole power from CB#48 but also from CB#51 but the coil does receive its power from CB#48.

I am unsure what the coil is there for but when you remove CB #48 you will remove power to the coil of the Throttle Motor Control Relay. Attached is a thumbnail with circles for that little black dot AND arrows for tracing the circuit to the ECM for everyones viewing pleasure.

I AM NOT SAYING THIS DOESN'T WORK. I am just saying that GaleForce IS right and we don't know what signal the COIL provides at the ECM for both the Steering lock and the Throttle Control.

You are wrong too please learn how to read a wiring schematic.

Your diagram is incorrect. The only connection between the SLR and TCMR is an 80A fuse that feeds the 4 fuses. It is the ECM relay that has a relationship with the TCMR.

Confirmed by this schematic from the other thread. (Image credit to GaleForce)

You want to know what is funny is I work on cars for a living and know how to read a wiring diagram ,I wonder how many people that are looking at this truly know what they are reading.

No not you Ubetit.

Yup, this is exactly how I understood the schematic! Thanks for the post!

I'm not trying to rain on anyone's parade, I just wanted to give you guys a heads up for potential problems. I guess you were well aware of this.

You're looking at it wrong. There's so much going on in that area of the drawing I can see where one might get confused, but just going of of this schematic the TCM relay is NOT affected by the S/L fuse.

Your wrong!!!

All of those relays are powered by the same wire with a fused wire branched off to the side for each relay the Node you are referring to is a junction point which goes to the Throttle Control relay it has it's own fuse but is branched off the same wire the S/L is.

I have no idea how you come up with this by read the diagram you posted.

Ok, I'm wrong. I see it now.

Here I thought only my wife got off on telling me when I'm wrong...

Thanks for making me feel at home

You show signs of being a big man to admit your wrong.

Have a rep and a smile.

Excellent work guys. I had thought about pulling the fuse if mine ever went to try and get it going. Great to know this solves the steering lock dilemma

Glad we could help

It feels good to give back to my fellow Z guys

if yours goes.. pulling the fuse wont help. its too late. have to pull the fuse while its in unlocked position.

Basically same concept as the wire, cept no cutting, no cost for harness / plugs etc.
