Summary of change:
I reused the old wires I think that might slowed thing down a lot. but I got to keep the nice sealing of the OEM wires. after working in the '''Black''' car in 108°F temps I notice the whole harness can come out easy. so I pulled it out and did a lot of the work in the shade http://www.vems.hu/files/MembersPage/KeithHargrove/loom_riped_out_of_car.jpg Then after the work http://www.vems.hu/files/MembersPage/KeithHargrove/reworkedharness.jpg == COP wiring == I used 2 sets of the VW harness part# 1J0-971-658-L http://www.vems.hu/files/MembersPage/KeithHargrove/harness.jpg == the COPs == part# 06B-905-115-N http://www.vems.hu/files/MembersPage/KeithHargrove/cop_in_head.jpg you need the short sparkplugs like a camerry I think the 24V use the right plug too. http://www.vems.hu/files/MembersPage/KeithHargrove/sparkplugs.jpg == Non-Working TPS == This is the old switch type every one that looked like this in the junkyard was a switch this is no good. http://www.vems.hu/files/MembersPage/KeithHargrove/switch_tps.jpg == Working TPS == This type is has a pot inside look for this type at the junkyard. the mounts are different but a ¼ inch chunk of plastic and a drill will fix that. http://www.vems.hu/files/MembersPage/KeithHargrove/pot_tps.jpg == COP Drive == == it is 5V so I need re-think this == I changed the coil mosfet resistors to 1K at Q3 Q6 Q9 Q12 Q16 Q21 jumped gate drive to output. added diodes out to ground this will clamp any negitive voltage on the outputs 5.1V zeners would be a beter but I did not have any. I ended up with a NPN driving a PNP giving me a strong 0 to 12V but I do not think it was needed. ---- == COP setup == |||||||||||| The pairs I will use so I can run wasted is || || '''L-jet Pin''' || '''Wire Color''' ||Transistor || number in setup || ECIII pin || cyl || || 2,3 || White,Yellow|| Q16,Q21 || #0,#1 || pin35,pin33 || 1,5 || || 18,11 || Purple,White/black || Q6,Q9 || #4,#5 || pin11,pin12 || 4,3 || || Spark7,part 6 || Purple/white,Green|| Q12,Q3 || #6,#7 || pin10,pin24 || 2,6 || ---- == Injection == Using old wires.
