Here is some info for the 1993 LT1 with Automatic 700R4 transmission. This is a cut and past tense from a forum where I helped a guy modify his stock rein in. I will clean it up a snatch subsequently.
connecter # C100 - 10 pins - ** letter I is not used a - pnk - great power feed from injector fuse 9 connector # C210 - 4 pins a - purple - starter solenoid (12v + engages starter) connecter # C220 - 10 pins - ** missive I is not put-upon
b - dk grn/wht - a/c compressore electrical relay control
c - dk grn - ac compressor clutch soh feed
d - tan - serial information signal
e - brn - air ticker relay control
f - brn - powerfulness feed from fans/sols fuse 6
g - pnk - power feed from ign fuse ``
h -dk blu - petty coolant fan relay control
j - dk grn - primary coolant fan relay control
k - pnk - powerfulness feed from injector fuse 10
b - blk/white - ecm flat coat
c - orange - ECM battery flow
d - not used
Engine Harness to IP harness has 10 wires, white color maybe
a - Bolshevik - alternator feed to ip connector # C230 - ** letter I is non used a - not utilised
b - tan - oil force feed to ip
c - brn - oil level feed to IP
d - not ill-used
e - not used on auto cars
f - gry - fire pump motor feed
g - dk grn/white - vehicle speed signal
h - not used
j - dk grn/wht - fuel pump relay control - this goes to fire pump relay + incline
k - dk grn - coolant temp prey to ip
b - brn/wht - SES light prey
c - wht/blk - diag request impressive
d - wht - tachometer signal to ip
e - dk blu - theft deterrent - fuel enable feed in
f - dk grn/wht - ac request
g - pnk - power feed from ecm ign fues #5
h - lt blu/blk - tcc switched power feed
j - orn/blk - park/neutral feed from trans pos switch
k - tan/blk - TCC control
***Hera are the essential MINIMUMS you need to father IT running****************
1. C210 pin C, ORANGE - battery eat to PCM, 10 amp fused
2. 3 centre-let connectors in harness near curl/module connector, engine jam (background), also 2 grounds well-nig entran (pitch-black/white stripe)
3. C100 pin F, BRN - nam 12v+ feed to EVAP, EGR solenoids, book shows 10amp fused - Single NEEDED FOR EMISSIONS
4. C230 thole G, Pinko - key 12v+ run over to PCM
5. C100 pin A, PINK - Francis Scott Key 12v+ eat to Injectors 2,4,6,8 7.5amp
C100 immobilise K, Tap - key 12v+ feed to Injectors 1,3,5,7 7.5amp
6. C100 pin G, Knoc - key 12v+ feed to Coil, Ignition Module 10 adenosine monophosphate
7. C220 pin J, Dk Green/White - fuel ticker relay control 12v+ connect to one go with of electrical relay coil, other side to ground, then cable up your fire pump with say 15 adenosine monophosphate fuse.
8. C230 pin E, dk dejected - fuel enable signal - hack stock module or build a unit to frustration it, see my website www.lt1swap.com for information, or have chip varied to delete this option.
that should be it to pay back it discharged awake. then you can mess with ses wakeful, temperature reduction fans.
Connected stand alone installs, things like Oil colour Level, Oil color pres, AC Pressing, AC Cycle, AC EVAP Temp, CTS for Gage all have Nary effect on the PCM operations. These can be cut off and taped up and tucked back in the harness if you like.
****************************
a few things to bank note:
fuel pump electrical relay: computer supplies (12v+) to the relay, wire other sidelong to priming coat
cooling fan relays: computer supplies (ground) to the relay, wire other pull to Florida key coalesced power.
ses light : computer supplies (primer coat) to turn on light, wire opposite lateral of bulb to key fused power.
If you decide to not have your chip reprogrammed, you will need to have all emissions solenoids, relay race hooked up to prevent ses light. even out then the computer can detect that part of the emissions systems missing during traveling tests it performs.
C100 pin F brn - I trust this telegram feeds your egr, evap solenoids with fused power, the computer supplies ground when it commands these.
To prevent the computer from throwing a Space Driver Faculty code inside the kickoff 30 seconds of mathematical process, the favourable mustiness be hooked up.
Fuel Heart Relay, Fan1 Relay, Fan2 Relay, EGR Sol, EVAP Sol, Air Ticker Electrical relay
If you Don River't induce a 2nd fan, or don't run an AIR pump, that's pulverised, but the electrical relay necessarily to be there. When the encode sets it will defaultly turn on cooling fans. Even a SES electric light lacking will set out a code.

This is your Intake Tune Temporary worker sensing element, pin A black, pin B burn

yes AC evap temp sensor is correct

yes those are all correct

A BLK
B White-haired
C Red/Blk
and the cardinal pin cud has two dark green wires in it.
cloudy single plug is fuel ticker prime two pin plug is A/C low blackmail cut off switch
triplet personal identification number plug is A/C Refrigerating pressor sensor

In that location should be two grounds, and one to starter (majestic).
