I support the comment about checking the condition of the wires at the terminations. The wiring on my injectors and on my Coolant sensor was very brittle at the ends where it went into the terminations. Disconnect them a few times and the insulation will crack and fall off. I expect that yours will be the same and you should probably plan to have to do some repairs, so you will need replacement crimp terminals. If you need to splice in some new wire on the ends, try to get a GXL, SXL or TXL wire type with cross link insulation. They are rated for 125 C operation. The primary difference between the three is the wall thickness of the insulation, TXL being the thinnest. Avoid the GPT class wire which is the most common, it is only good for 80C. The best wire would be Teflon insulated stuff; but, it is pretty hard to source.
