[Gmecm] TBI Swap - Iron Duke Tech IV :UPDATE:

[Joe Simmons]

Good move on the S10 stuff.

If I'm not mistaken, you need a 2 pulse/revolution square wave unit.  JTR # 
2PRS or 2PRS-EXT will work right for your application.  Bypass all the DRAC 
wiring and wire the output wires to the ECM to your speed sensor.  I used 
one of them on my 91 S10 when I went to a TH350 transmission.......moot 
point, now...I pulled the injection back off.

Contact me off-list at birdfarm at direcway.com and we'll work out something on 
my surplus unit, and possibly a Helms wiring diagram.
