No. First the 68 repeated three times, then 12 repeated three times.

The pins in my plug are arranged a little different for some reason. That's why I thought it was upside down. But I think I got the right code. It flashed 68 then 12...I'm assuming that's code 1268(12 meaning system is working).The only thing I can find online so far for 1268 is a brake pressure module. Does that sound right? Still trying to get pics on this. Found this on truck mode central The following is a list of the OBD-I trouble codes for the four wheel anti-lock brake system. *Code 21: right front speed sensor or circuit open *Code 22: missing right front speed signal *Code 23: erratic right front speed signal *Code 25: left front speed sensor or circuit open *Code 26: missing left front speed signal *Code 27: erratic left front speed signal *Code 29: simultaneous drop-out of front speed sensors *Code 35: vehicle speed sensor or open circuit *Code 36: missing vehicle speed sensor signal *Code 37: erratic vehicle speed sensor signal *Code 38: wheel speed error *Codes 41 through 54: control valves *Codes 61 through 63: reset switches *Code 65 and 66: open or shorted pump motor relay *Code 67: open motor circuit or shorted BPMV output *Code 68: locked motor or shorted motor circuit *Codes 71 through 74: memory errors *Code 81: brake switch circuit shorted or open *Code 86: shorted anti-lock indicator lamp *Code 87: shorted brake warning lamp

Yep. Did that. The strands of the wire kinda unraveled as I pushed it in the holes, even though I twisted the ends tight. I'm gonna try a solid wire tomorrow and see if any difference. Also, the plug looks like it's upsidedown compared to the picture I saw, and the one in your reply. I'll try to get a pic of mine up tomorrow.

My 95 K1500 abs light came on about a month ago. It will come on during initial start up, then goes out. Then it comes back on once I start driving. I read a post on here on how to use a jumper wire in terminals A and H to retrieve abs codes. I did it, and there were no flashes. Any ideas? I don't want spend money on an OBD 1 if I don't have to. I have a car md, but that plug doesn't fit this vehicle. Thanks in advance
