I now realize I forgot to mention that I'm running a GTi cluster, while the original is the black face 1.6 SR/GX one...
Compared the plugs, and the brown plugs are different:
1.6 loom has 4 wires on one side (green/yellow-stripe, black/pink-stripe, orange/black-stripe, pink/no stripe)
2.0 loom has only three wires (orange/black-stripe is missing).
Will do a test run with the original cluster to see if everything works with that. Any tips on how to run the GTi cluster?
Couldn't figure out where the plug pictured above is supposed to go either...
