88 suburban-engine swap, now no power

Ok last fall my dad's suburban popped a head gasket, toasted the block. We just got done installing a brand new crate engine, only to find out it won't even crank over.
EVERYTHING has power except:
the horn
the brake lights
the radio
the fuel pump
The solenoid is getting power, the distributor has power
New batt, new starter
It seems to me like a body ground, but we've tried making ground between the body/frame, body/engine and every other possible combination.

Update. After asking AGAIN AND AGAIN if he hooked everything up correctly, I had the zany idea that the starter was not hooked up correctly. Turns out he had the solenoid wire on the "R" terminal instead of "S".
After pokin his ribs about getting old and some good laughs, It cranks just fine.
Also turns out that brake light switch had become corroded from sitting
However there is still:
NO HORN
NO FUEL PUMP
NO RADIO
What would these circuits have in common? None that I can think of.
ALSO I jumped the A and B terminals on the data link conn and cannot even get the computer to flash a code 12, aka All Is Good code
