anyone have a pinout for the 87-90 clusters handy?

technically the harness side but I can figure it out from there. 

 

the goal is to simplify my life by using a junkyard connector to power up a cluster and check for LED polarity correctness.  it's a serious pain in the butt to do that in the truck or one LED at a time when you're doing 7 or 8 clusters worth.  :D

trying to go through my stockpile and refurb them for selling.  :L:   It's easy enough to do a quickie test of gauges by installing them in the truck for a hot second, but every single LED has a 50-50 shot at being backwards and I'd rather work through all that in the comfort of the A/C in the house :D  

 

all this comfort is brought to me by this little guy.  what a fabulous invention!

Just wait until you have interchangeable custom made test jigs to test all gauges and lights at the same time, two lab power supplies, a signal generator to sweep the tach, precision trimmed pots to sweep the gauges, and the ability to completely strip a cluster to the case and put it back together blindfolded.

 

It'll be sooner than you think!

That does look handy.

 

Another good way to get reference voltage is to look at power supplies you can find in ham radio catalogs.  I've been eyeing one so I can run one of my extra car radios in the house.  They let you adjust the voltage so you can run the 13.8V or whatever you'd get while the vehicle is running.
