wiring harness pinout?

[SkysTheLimit]

Anyone have a diagram / know where I can find one of the pinout on an 88 K5 Silverado for the wiring block on the firewall in the engine bay? The one that the TBI harness & headlight harness hooks up to? I want to make up a custom harness since I'm ripping out the computer and want to keep the stock guages / switches / ignition for now.

Is it in the Haynes manual? (can't find mine but will look harder if it has the info I need)

thx

Don't know about Haynes, but it is in the GM shop manual. Sorry, I don't have one for that year (or any TBI year for that matter).
