huh? Should have used wire taps and just crimped it on to the wire from the pcm and put in a long wire to the switch on the other side of the crimp. The pins on the PCM are labeled and red and blue should be obvious...

neither of my wires on either 42 or 33 was red or blue on either side and I did just crimp the wires, but I crimped on to the 43 and 33 on the same side that unplugs from the PCM, didnt know you had to crimp 43 on the one closest to the red and 33 on the other one

No no no, the big plastic connectors on the PCM. There are 2 of them; one is red, the other is blue. Per the diagram, you need pin 42 on the blue connector, and pin 33 on the red connector. The color of the actual wires should be dark green and dark blue...

I didnt catch on to that at first and hooked up both wires on the same plastic piece, think it could have messed up anything? My ABS and parking brake light is still on.. bugs the crap out of me
