Default ver8 207 engine harness and ecu into 02 wrx

Ok so I have some questions and issues, I did this swap and it worked great for about 1k now im starting to have issues, I have now started looking at the fsm wiring for both and my issue I believe is in in a ground in the black engine harness plug ( if I can get it running, and I move that plug it dies haven't gotten it running again so not sure which wire it is, but I am getting a cel for the coolant temp and tps, both share the black with a green stripe ground wire) Well that ground goes to the sheilded sensor and ground junction thing, well between ver8/7 and usdm wrx they are way different. It now actually makes me wonder how these swaps are even possible.

Has anyone else had this issue before or is there a common fix for it????

Also if I check the power and ground and signal on the tps and the map which uses both the same power and ground, I actually get a weird number, I get 5 volts. On the power and 7 volts on the ground, and .02 on the signal, what would cause a voltage split between the two??? Any. Of the grounds in that stupid junction thing? ?
