I followed the instructions in the tech article to convert to an electric speedo cluster and well let me tell you things didnt work out as planned. I have the cluster here and looking at the routing on the back of it I can tell why. Let me explain the problems I am having. The brights light is on all the time, the left turn signal flashes the right arrow, the right turn signal doesnt flash any arrow, but pulses my fuel gauge, the tach doesnt work, and the speedo acts as if it is a tach.

It appears that the wire that now goes to the brights light was origionally went to the green wire on the speedo mounted vss. The right turn signal wire appears to go to one of the fuel gauge spots. What was origionally the left turn signal now appears to be the right. The wire that origionally went to the brights is now running to one of the tach wires. A spot that origionally did nothing but has a hole for a light that may have been used in another application is now going to the other tach wire.

Well, I am not sure that all of that is exactly correct but my mind is starting to go numb from tracing it all. Anyway, I just basically need the diagrams if anyone has them.

Thanks

I swapped clusters from an 85 to a 87. They are totally different.
I needed to cut and paste about 10-15 connections on the back of the cluster. Are you going from cable to electric spdo? You can look at the flex board on the 85 cluster and figure out where the sig. goes then cut and paste the 86 cluster to match. The temp., oil p., fuel, volts are all in a different place.

 

Yes I am going from cable to electric. Physically at least, my bat and tem are in the same spots, but my oil pressure and fuel are swaped. I did think about tracing them, but it would be a lot easier if I had diagrams of the pinouts of the 2 connectors so I could just switch which wires go where. One prob I am running into is that some of the gauges have have more than one wire that leads to them and I wouldnt know which ones should go to where exactly. Did you switch which wires go where on the connector or did you do it some other way? Thanks for the help.

I cut the traces on the flex board and used wire jumpers for the new connections. I didn't want to change the wire harness connectors so I could swap back to the stock cluster if I wanted. I have the pinouts for the 85 it's in the shop manual. If you give me a fax # I will try to get it to you.
