ABS Removal - Wiring

[Champagne]

ABS didn't work on the car, so to simplify things I have removed it. I purchased a non-ABS brake master cylinder and have made hardlines. I unplugged the ABS ECU from the drivers rear quarter.

This is on a 1990 Nissan 240SX.

My question is, can I just cut the plug/wiring out from where it branches off the main harness, heat shrink the ends, and leave it at that?

Or is it interconnected to other things, i.e. it acts as a shared ground. To remedy the ground issue, would that mean just taking the ground wire and hooking it up, and cutting everything else.

Eventually I'd like to strip it out of the entire harness, but thats a project for another day.

Also the 3 plugs in the engine bay that plug into the acctuator, can these be cut as well, same plan as above?

I appreciate any help or advice!

The ground wouldn't be where the connector plugs into the device. Why not just leave plugs open in case down the road you wanted to try and get it to work again?

I suppose that is a possibility, I was hoping to clean up the engine bay a little, remove unnecessary items. Because of the custom hardlines and removal of the ABS sensors, I don't forsee ever going back, hence why I would like to remove everything related to it.

I can relate... I've put way to much time into cleaning up wiring... if it's something you knoooow you're never using again, then ya you're fine just cutting and it doing like you said with shrink wrap. Isn't there an ABS fuse? If that isn't a shared circuit, you could just pull the fuse and that would make sure you wouldn't get a short from the cut wires.

Are you going to be selling off all the ABS stuff? Hubs too? Plenty of autocross guys (including myself) would certainly be interested if you were !!

I believe there is a fuse, I'll look into that and pull it if there is.

But to your knowledge the ABS isn't tied to anything else? I'll definitely read some wiring diagrams before cutting anything, but others input is always helpful.

No hubs as I just removed the sensor and put them back into service. Most of the sensors were frozen in unfortunately and had to be drilled/cut out.

I do have the actuator, hardlines and ECU if someone were interested. Also have the ABS front calipers/brackets (I believe they had slightly different pads/rotors, as most places list two part numbers, but I've never actually compared).

Curious as to why you would use it for autocross? To lower your class, i.e. does removing it bump you up? PM me if you are interested in it. Its just sitting so we can work something out. Unfortunately depending where you are shipping might not be worth it as I'm up in the Great White North eh.

Has no affect on *most* classes and it is one of the few driver aids that actually help. Finding the point right before lock up is almost always going to take more time than mashing the pedal in an ABS car. Plus, without the possibility of a lockup, you're not going to flat spot your expensive tires.

I remember briefly looking at the wiring diagrams for ABS before and it looked pretty self contained. Can't imagine it would give you problems removing it. Maybe someone else can confirm that.

On s14 it is very much self contained. You may need to do some unlooming to separate it out the right way. I recall being able to merge s14 abs into my rb harness without any cutting or soldering of wires. Instead of cutting the plugs and leaving the wire there I'd suggest extracting the wires entirely if u want a clean removal.

Good info, thanks guys. Much appreciated.
