Anyone worked with the 16196397 yet?

If so, I am worried that the computer, DRAC, and half of the associated wiring is under the dash-although there is a computer-shaped box mounted underhood in a black plastic holder, bolted to the brake master cylinder.

this is an early form of rear anti lock commonly found on 93 and up models. you should also have a second block after your proportioning valve with a couple wires going to it. if you have a VSS than more than likely you have the most of the 93 components in the dash.

Excellent, so the truck DOES have antilock brakes...there's a shitload of wires going into that black box.

I am hoping that I have a DRAC under the dash that's on the fritz, as my speedometer drops out, flings around, pegs at 80+ when you're doing thirty, etc on a regular basis.

the speedo on the ranger I beat around in does that, but I assumed it was normal for all worn cable-driven setups. I could be wrong, but I want to say that in 89 or so, all S/T trucks went to speed sensors rather than cables?

I think it varied for a couple years based on MT or AT. I know my buddies 89 was cable driven with a sensor in the instrument cluster for the speed signal.

My 93 has a VSS in the tailshaft housing, no cable. If it was cable drive, a new cable would fix it, it normally means the cable is broken in the housing and the broken ends are catching and turning the speedo-not uncommon. When the ends slip apart, the speedo stops.

Supposedly the changeover happened in 88, when the Tachometer went away. I'd love to get a pre-88 cluster, transplant the electronic speedometer, and have a functional tachometer on the dash...

Picked up some 0280155811 injectors this week, 36lb Bosch injectors from an L67 3800 supercharged. Also got a 58psi fuel regulator and rail from a 3400, so I should have plenty of fuel now. Also got some more aluminum stock to make the upper intake, throttle body flange, and the idler pulley bracket.

The injectors are supposedly the same ones in the Corvette ASA tune, so hopefully getting the injector settings correct won't be difficult.

you could grab the injector offsets from a L67 calibration as well. I've done that before for some swaps, it does take some math to translate between the two though, especially with the ridiculous injector offset resolution of this PCM.
