After swapping succesfully an SR5 cluster on my 1988 20R everything works but dash lights are not working the cluster doesn't light up when I hooked up the old one dash lights work! Any help would be greatly appreciated. Thank you

 

well start with the obvious, bulbs...if not bulbs then its something in the circuit of the new cluster thats messed up, could be hard to track down...if you can't figure it out I would install some LED strips like I did on my cluster bypassing the light circuit on the new cluster.

 

joeynational, thank you for your reply and your idea on the light strip. My old cluster lights up and the new cluster doesn't light up when I plug it in.

 

joeynational, all lights work now was a loose bulb connection Thanx again for your help!!!!
