jamesinc;131252 wroteSo you're trying to wire up a late cluster with the electronic speed signal onto a '77 wiring harness right? Can you post the pinout you've got now?
Yep thats right. I havent put together the speed signal plug yet and wanted to get all the other instruments working properly to do it one at a time. This is what i have so far.
Half Moon (AKA Conn 32)
1 - Grey: Fuel Sender
2 - Brown: Parking brake
A - Blue/Red: 12v
3: Not used
4 - Black: Earth
Full Moon (AKA Conn 31)
1 - Grey: Brake failure (Was 31.5)
2 - Yellow: Temp sensor (Was 31.10)
3 - White/Red: Highbeam indicator (Didnt move it and it works atm)
4: Not used
5 - Black: Oil pressure sender (Was 31.11)
6 - Not connected yet, will go to fuel ecu for cruise and idle control.
7 - Blue: Indicator
8 - Green: Indicator
9 - Blue/Red: 12v (Spliced from 32.A)
10 - White: Cluster lighting ( Not connected yet)
11 - Red: Alternator (Was 31.9)
12 - Blue/Yellow: Bulb Failure warning (31.2)
It seems like its all pinned out correctly but now I'm not so sure :S
