Hey guys, Hope everyone is holding up in this crazy time. I have a 91XJ that is pretty modified from the PO. Just today i have little power in Drive or 3rd. Reverse/ Low are fine. Very similar situation to this thread.

I do not seem have a TCU connected. Rather the yellow/ blue/yellow wires are spliced (pic attached). All yellow go together and all blue/yellow as well. Then they are tied into the black unit which i am not sure what to call that has a jumper conductor between the two. I messed around and made sure everything had a solid connection and swapped in a new fuse/ fuse harness to no avail. Anyone have any insight? It was running fine last time i started it, all i did in between was swap in some new speakers and did not mess with that harness at all. I appreciate any info you might have.

Here is a picture of what i believe was the TCU but it is not connected to anything, just wires spliced.
