Chris,
Although not entirely related to you BUILDING harnesses, can yuo still source the connectors and pins for air temp/coolant temp/TPS/MAP (map and fuel injectors I can still find........) etc.?
I'm right into the TECgt harness, but can't seem to find the connectors I used when I did the E6X harness. If I ahve to buy the sensor pack to get them, I guess so be it, but if you've got a source I'd gladly pony up
(may pony up for you to get me the sensor pack anyways

)
PM me, or post back here - thanks!!
