We have recently purchased a used 5FGC25 lift, upon giving it a good cleaning and tune up we found the electrical system to be a complete hack job. The lift ran fine when it was purchased and now has little to no spark, Coil pack tests fine (1.8-2.0 Ohms) plugs are gapped, timing is correct, fuses are good. Im assuming the brittle wiring and previous hack job is causing my problem. If any one can direct me towards a service manual or wiring diagram that would be very much appreciated.

I should mention I am not intending to score copyright material, I legitimately need appropriate documentation in order to trace out this issue. I have been in touch with Toyota and have had no luck in purchasing any information from them.
