SR5 tach cluster upgrade question...no tach
 

I threw in a cluster i pulled at the yard today. the cluster came from an 85 4runner. Im trying to put it in my 87 dlx pick up. For some reason the gas gauge is not moving and my tach is not working. Everything is plugged in correctly. Is there something im missing? I have searched and searched and every thread shows just the oil pressure sender and nothing more. Please give me some ideas. I looked by the coil and tied in to the harness everyone taps for after market tachs i have a blank one wire plug.

Ijust turned the truck to acc and saw a small jump in the tach. When its running the only moving it seems to do is bouncing from it not being mounted and the truck starting.

Thanks

Nevermind i found the answer. Easy fix. The more i turn it on the closer the gas gets but its freezing cold and im guessing kinda slow in the cold. I will try tomorrow.

Thats the answer to the non working tach just for the people searching like i was. Its a screw on the back that needs to be wired to the plug i was talking about.
