im swaping a 5.3L 4L60e in my 82 c10, and i bought an 87 electronic guage cluster so my speedometer will work with the tranny. i need to repin the guage cluster can anyone help on how to do this. thanks in advanced

 

the cluster you bought, is it stock?

 

yes i bought a stock cluster from an 87 c10.

 

Sounds like your making progress! I have a Chilton's manual for a 81-91 C,K trucks. It has all the pin outs you would need.

 

yeah i just need to send the harness to nelson performance. finish the clustrer, rad hoses, and litlle misc things. how did you get your speedometer to work? did you repin your cluster?

 

Thats the plan, for the past 2 years I've been running with my Garmin

 

i found this on the ls1 truck forum, but unfortunately i dont understand it. do you know how they did it? its an excel file.http://www.ls1truck.com/forums/lsx-t...ge-wiring.html

 

I've chatted with pcmcobra a time or two about it, he's on this site too....

Its just like he said
"I swapped my 86 cluster with a 91 burb cluster. Had to repin it, was not hard. I have a spreadsheet somewhere...
After repinning, only thing you have to hook up from your harness is the speedo wire, and that pins into your cluster "plug".
I can email you my spreadsheet if you want, hope you can understand it. Best thing to do is if you have it, the cluster plug with all the wires from the 91 cluster, take out one wire at a time from your old "plug" and color match to new "plug"."

If you get a wire diagram for a 82 like your truck, and a 90 or what ever year your cluster is. Its not to bad, I started on mine and just never had time to go back and do it. The pins come out really easy with a pocket screwdriver or O ring pick.

 

so i just pull the wires from the my 82 plug and put them in my new 87 cluster plug? im sorry, i dont know anything about automotive wiring thats why im sending my harness to nelson performance.

 

Yes you will be swapping wire locations in your 82 to make it work like the 87. Are you sure that the 87 speedo is electric? I was thinking it was still cable???
