1G No power to cluster

[90GSXBlue]

Working on my 90 gsx with a rywire engine harness, and stock chassis harness. The issue I’m having is some of my electrical systems work, some don’t. For instance, fuel gauge works along with speedo obviously, but oil press, water temp, boost and rpm do nothing, warning lights come on when the key is turned on but not sure they’re actually working. I also have no vss reading in link and no gauge cluster lights when I turn my lights on. I’m thinking it has something to do with the rywire harness swap and something not hooked up. Anyone ever had this issue like this with the rywire? Also Power windows and power locks don’t work, not sure if it’s related but thought I’d throw that in there.

Thanks for any help.

Idk about the rywire stuff, but alot of those functions get their signal from a jumper harness that comes off the ECU. You could check and see if there is an extra rectangular plug near your ECU that is either unplugged or doesn't have all the wires pinned?

Any idea what plug number that would be (for example c-67)

c-67 i believe is the correct connector, HERE is a good thread for identification.

Thanks that's the great place to start.
