I've been searching for 2 days and found it once for sale but lost the link. Free would be better. Lol. I'm switching from an 88 crap cluster to a 86 SR5 and I need the pin-outs. Thanks for the help. I tried the URL with "granola boy" in it and it seems to be dead.

Don't know of anywhere to get that anymore. It's too big to email as an attachment. But here are the pinouts from it.

Thanks. Ill stare at this and see if I can decipher something. I'm really intimidated by wiring and I hate to even try this. No choice since I'm invested in the cluster and now my dash is apart. I have no idea which wire is what. And, I do not own a voltmeter.

I would invest in one for this job you can get one for cheap at walmart or radioshack. Not to mention they are an invaluable tool for troubleshooting many things on your truck. You don't need anything fancy just need to be able to test for voltage and resistance.

Ok...so why do some say "Connector A 4-2" what is the -2 part mean?

brianh699

Depending on what option you have that pin serves different functions for example on Connector A 4-1 is with ECT or Auto tranny 4-2 would be with the manual tranny

Thanks again. I shoulda never ˟˟˟˟ed with this thing. I'm lost on this and can't drive now.

I have an 88 and just bought the SR5 cluster from an 85 and plugged it in. Worked perfect.

You MUST change the oil pressure SWITCH from the 88 non SR5 to the SR5 SENDER or you will fry your oil pressure gauge.

So I've got speed, volts, and gas working. Unplugged OP switch before I got started so I knew it wasn't gonna work. No tach.
Temp gauge goes about mid way at cold start. 70 degrees outside. After driving a few minutes it dies. I cut off the switch and start the truck back it goes back mid way. Not working right.
