I have a 97 TJ. The 4 cylinder engine cratered.
I bought an 03 TJ Sport that suffered a cosmetically bad rollover.
I stripped the 97 to the tub and frame, sanded it, painted it and robbed the motor mounts from the 03.
I have robbed everything from the 03. From radiator to fuel tank, from ECU to taillights, from steering column to dash, from heater and AC controls to back seat, from cruise control to EVAP, fuel lines, brake lines..... ALL OF IT.
With a few minor required modifications, I’m stuffing it all in the 97.
The only thing I have not kept are the 03 axles. They had 3.73 gears and besides that, the the front axle was bent anyway (upper ball joint is bent in about a half inch - trash).
It means I’m keeping the 97 axles with the 4.11 gears.
Here’s my question(s). The 03 has ABS system. I have no such sensors at each wheel to plug the wiring into.
If I simply leave the wheel sensors unplugged, will I just get an ABS idiot light (the computer disables the ABS system) and that’s the worst that happens? Or will it freak out in some other way I haven’t thought of?
And just for fun, here’s another question. As I understand it, each wheel has a grooved ring and an electromagnetic coil that reads the electromagnetic pulses as the wheel turns. If the wheel stops faster than the ECU thinks it should...engage ABS, monitor wheel speed, etc.
I’ve also read that the crankshaft position sensor is the same type of sensor (essentially) - reads magnetic pulses, determines RPM (again, as I understand it, could be totally wrong).
If you tapped the signal wire coming from the crankshaft position sensor (which is reading electromagnetic pulses) and fed that into the signal wire that would normally be plugged into the ABS sensors at each wheel, would that cause the computer to always assume the wheels are turning and therefore never engage the ABS, but also never trigger the ABS error or light? Could I fake it out that way?
I’ve used everything else, so why not use the sensors and control from the 03 axles? Because I hate ABS. I’ll stop it myself, thank you very much.
Or should I just disable the damn light (because I hate error lights, too)?
Or am I totally overthinking a tiny issue? Just leave the sensor wires unplugged and live with the stupid light?
