1991 Suburban Speed Hut Speedo install problem - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey Guys,

I have just installed a Speed Hut electronic speedometer in my 1991 V1500 Suburban. 5.7 TBI, 700R4, 241 transfer case.
Long story short....it does not work. The error I get when setting up the speedo is "No Signal". I am hooked to the pin 18 light blue w/black line which I believe comes from the DRAC and I expected it to work. I tried ground and no ground.

Any ideas?? I could use some help on this.

Thanks
