Hey guys,
I realize I'm late to this thread, actually someone just emailed it to me and asked if I could help. I supply patch/conversion harnesses for all different types of setups, here's an example of one that we do:
Going from the late version 3SGTE ECU to the early or vice-versa:
As you can see the wires, after being soldered to the header and heat-shrinked, are also epoxied in place to secure and stress-relieve them (otherwise they could easily break off). The pins on the ECU side are all crimped using OEM terminals and are machine-crimped. This is done using all new parts.
I've done quite a few different setups, like running a 4AGE (turbocharged) with a 3SGTE ECU, and could easily make one to go from an ST165 harness to any version 3SGTE ECU. Typically harnesses like these are around $150 or so, I'll have to see exactly after I build a couple if the price needs adjustment.
Feel free to ask any questions you might have
