72 K5 Blazer Wiring Problem

[A1AUTOMOTIVE]

Hello my name is Gilbert. I work at an automotive shop in Orange, CA. We have a 72 Chevy K5 Blazer with a 350. Somebody stripped most of wiring from it. I was hoping I would be able to find some help here. We have Mitchell OnDemand 5 and AllData but they both have no wiring information on them. I have been on google looking for diagrams but no luck so far and found you guys. Any help would be appreciated. Thank you for your time.

Bam!!!

You should be able to enlarge those to get the detail you need. Good Luck.

Thanks so much Greg. Quick question. On the second picture is there another part to that? My tech says there appears to be pieces missing. I see they are named schematic 1 and 2. Is there possibly 3? Thanks again.

There's actually two others, one for instrument cluster / ignition and one for the rear taillights, etc.

Those came out of the original 1972 Factory Service Manual.... I found those online many years ago, maybe someone else has a link to a more complete set of online schematics???

Darn. Ok yeah tech said missing diagram for instrument cluster. Ok no problem thanks again though Greg. If anyone knows where to find those it would be much appreciated. Thanks.

You should be just down the street from The Truck Shop on Batavia just a mile South of katella on the East side of Batavia and just North of the R/R tracks. They will have the proper diagrams for wiring you need on the '72. You may have to buy them though.
