Im in the process of wiring up my speedometer however ran into a problem. I have put in the speedo gears in and have already got a electronic speedo gauge. I bought a speed buffer from gm for an 1990 camaro. However i have the v6 dash harness and i need the pigtails for the speed buffer. Gm said that they dont have it but i think they are being stupid. If anyone could tell me where to get these two pigtails and or give me a part number i would really appreciate it alot. Thanks.
