Is there a known company that can make a custom LC100 1ZF-FE engine harness? And even better than OEM, my harness is done and has reached the end of its life. The first thing that happened to me while I was driving was that suddenly the engine started shuttering every time I pushed my foot on the throttle. Until it turned off, I kept checking the fuse box for any problems until I realized it was from the coil wires, which were broken and so hard from the sun and years. and when I attached the wire correctly again, the car starts now, fortunately, but the rpm stays at 500–700, like a cammed engine, and then shuts off.
