Oil pressure - P/N GTOP80W model# 881CU

water Temp - P/N GI-WTW model# 825CU

voltage - P/N GI-VMW model# 830cu

fuel level - P/N GI-FLW model# 810CU

Pyrometer - GMPYDW

Scot, ditto on what MadPoodle said. The blue wires are always for the lights on the gauges. Purple = ignotion, black = ground, light brown = oil pressure, uhhhhhhh I forget, it's been too long.

I'll try to link a wiring diagram to this post. If you go to a site called MERCURY MECHANIC, it's there. Use the new diagram. I spent around 100 hours on my dashboard wiring, buss bars, etc. My underdash looks like a 747. All heatshrun and squared off with ties. I used the diagrams on allof it.

Scot did you also save the plug ends from the dash? If so cut them off leaving a few inches of extra wire you can wire up the dash using the correct colors then splice it in to the ols plug. It is nice to be able to unplug the dash for any kind of work, it is a bugger working upside down! LOL

Hey Scotty, talk CAPTWK into coming over and helping you. The wiring he did on his Z-33 Crossbow is AMAZING! It looks better than factory, and he started from scratch.
