89-91 Suburban speedometer
I have just about finished up my swap of a 2004 tahoe 5.3/4L60E into our 85 Chevy truck. I decided to use an 89-91 cluster to get the electric speedometer and not have to change the trans to cable Speedo drive. I did have the PCM reflashed by Brandon at LT1SWAP.COM and let him know which speedometer I would be running.
However, took my first drive this past Saturday and found the Speedo is not working. I would like to check my wiring before I declair this the speedometer is bad. I know the Suburban cluster has 3 leads (power, ground, input) for speed and the PCM has 2 leads. Can anyone tell me how they wired theirs? Thanks in advance
