speedometer wiring for 01 5.3 into 91 gmc k1500

HAHAHAHA...Yeah, my tires are pretty flattened out at this point too after sitting for a year...lol...good news is I have a single wiring issue with a fan relay to tackle and this is DONE. I put the truck back up on the rollers yesterday, and did some final street tuning...had to lean out the idle a bit but other than that...speedo and ECU were good for speed signal and looks like the registered speed at the gauge was as good as it always was...probably a tire thing because it always registered a little faster than actual.

got my efan wiring done and balanced my square bfg's (23 OZ TOTAL!)

drove it another 15 miles before my transmission blew lost 3rd and 4th

the good news is that it was still under warranty (bought from local salvage yard with 90 day warranty)

and they supplied another one and extended my warranty to 6 months

this time i'm having my trans guy go thru it (master kit,beast sun shell and 29 tooth sprag) no need to build it any better than that and the 5.3 is stayin stock and I don't tow anything

going to see if this helps me, I've got a 1997 GMC with a 2000 4.8l swap. I've driven it a total of two miles....no speedo or trip working. The ABS is on as well. Now that being said, the speedo sensor was "Y'd" to both the OBS ecu and the NBS ecu. Supposedly, the signal was split in order for new ecu to run shifting duties and the old ecu to deal with gauges.

Any suggestions
