So I pulled the TBI stuff from my friends 90 Suburban. I checked the numbers and it is a 350 c.i. set up (ECM 1227747 BCC ASDU). I was not able to get the K.S., it was "stuck". I took the intake to the machine shop Thursday so they could hot tank it and he gave me the 4 shims/spacers I would need to put the intake on my heads (the four ceneter bolts will not line up). I sorted out the wiring and cleaned most of the other parts.

When I was doing the wiring I came up with a few more questions:

On the Oil Preasure sensor there are three wires...The light brown one went to the fuse block...Where does it go? Gauge?

I think I have the rest of the wires figured out except the ADAL connector:

Can you please guide me as to where these wires go?
A-BLK/WHT
B-WHT/BLK
C-DRK BRN
E-ORNG
F-LT BRN/BLK
H-White

Also, I belive it is the neutral switch (one PURPLE/WHT and one Wht wire) has a jumper across the wires at the connector under the dash. What do I do with this?

I can/will post pictures soon.

Thanks again for all the help.
