BP Automotive — Direct Fit F-Body A/C Setup Guide #
Purpose: Help you choose the correct A/C options when ordering a BP Automotive Direct Fit harness for supported Camaro / Firebird (F-Body) platforms — so the harness is built for your A/C layout the first time.
Troubleshooting will be added in a later update.
Start here: Direct Fit A/C uses factory wiring #
All Direct Fit harnesses use factory A/C wiring. When you order A/C Yes, the harness is built to work with the vehicle’s factory-style A/C path — including compressor wiring.
If you remember only a few things:
- Pick the correct A/C Yes/No and location at checkout — that is how we build your Direct Fit harness.
- Wrong A/C option = wrong build. These harnesses are custom-built and not returnable / exchangeable.
- All F-Body Direct Fit platforms must use an F-Body operating system in the PCM for A/C to function correctly.
- Fan wiring is not in the engine harness — fans stay on the car / forward-lamp side.
- PCM can be 09354896 or 12200411 (either works on all applications).
- Check lead time before you order: Current lead times
Harnesses covered here:

Step 1 — Decide what A/C situation you actually have #
Before you open the product page dropdowns, write this down:
- Keeping factory dash / HVAC in the F-Body, or deleting A/C
- Compressor location you will run (factory location, relocated / other, none)
- Which Direct Fit SKU you are ordering (H800 / H750 / H700)
- Confirm your PCM plan uses an F-Body operating system (required for A/C on Direct Fit)
Quick forks we see often in tickets:
- “Does the Direct Fit harness include A/C?” — Yes — factory A/C wiring (including compressor wiring) when you select an A/C Yes option; selecting No builds for no A/C.
- Customers expecting fan control wires inside H800 / H750 / H700 — fans stay with the original / forward-lamp side.
- Mixing this guide up with the 1999–2002 full-size truck/SUV A/C Update Kit — that kit is not an F-Body Direct Fit A/C part. See Step 5.
Step 2 — Open the correct F-Body product page and find the A/C option #
H800 — LT1 → Gen III LS · H750 — 1998–2002 LS1 F-Body · H700 — LT1 24x conversion
Air Conditioning choices (confirm live on each page):
- Yes Factory Location
- Yes Other Location (Use Notes Section Below)
- No
Notes that matter for A/C / cooling:
- Fan wiring is not included with these F-Body engine harnesses — it is part of the original / forward-lamp harness.
- A new factory firewall grommet is included on the engine harness path — still plan A/C location in the options so compressor / A/C leads match what you are keeping.
On every page: scroll the full description and use the option / part-guide photos before checkout.
Step 3 — Choose the A/C option that matches the compressor you will run #
- If you are deleting A/C, choose No.
- If you are keeping A/C in the stock compressor location, choose Yes Factory Location.
- If the compressor is somewhere else (custom bracket, relocated, unusual package), choose Yes Other Location and describe it in the order notes (a photo helps).
- Do not guess “close enough.” Location is how the harness is built.
Ticket-driven tip: Factory Location vs Other is still a real build choice even though fans stay on the car side.
Step 4 — Platform specifics (H800 / H750 / H700) #
- H800: 1993–1997 LT1 car, Gen III LS swap — A/C Yes factory / other / no.
- H750: 1998–2002 LS1 F-Body — same A/C Yes/No style choices.
- H700: 1993–1997 LT1 with EFI Connection / TorqHead-style 24x conversion — same A/C Yes/No style choices; PCM can be 09354896 or 12200411.
- Fans: do not order expecting cooling-fan wiring inside these engine harnesses. Fans remain with the original / forward-lamp side of the car.
- Factory A/C wiring for the Direct Fit path is selected with the A/C dropdown — that is separate from “where do the fans live.”
- PCM must use an F-Body operating system for A/C to function correctly.
Step 5 — Related parts note (what is not for Direct Fit F-Body) #
Air Conditioning parts category #
Browse fittings/sensors as needed and read each product description before buying.
1999–2002 Silverado / Sierra / Yukon / Tahoe / Suburban A/C Update Kit #
1999–2002 full-size truck/SUV A/C Update Kit (often referenced as kit 1018)
- For 1999–2002 GM full-size trucks and SUVs only
- Not an F-Body Direct Fit A/C part
Step 6 — PCM / operating system: F-Body OS required for A/C #
All F-Body Direct Fit platforms must use an F-Body operating system in the PCM for A/C to function correctly.
That applies to:
- H800 LT1 → LS F-Body
- H750 1998–2002 F-Body
- H700 LT1 24x conversion F-Body
Also remember:
- These Direct Fit LS paths use drive-by-cable and P01 PCMs. All applications can use either PCM service number 09354896 or 12200411.
- If BP Automotive programs/tunes your PCM: we need to know whether factory A/C is retained or deleted, and we program for Direct Fit A/C on an F-Body OS.
- If someone else tunes it: they must flash/use an F-Body operating system and enable A/C correctly for that OS — or A/C will not function correctly even with the right harness options.
- Fans staying on the car side does not remove the need for the correct F-Body OS and A/C programming in the PCM.
Step-by-step flow at checkout (F-Body Direct Fit + A/C) #
- Confirm you need a Direct Fit F-Body SKU (H800 / H750 / H700).
- Open the correct product page and complete non-A/C options (year, engine, injectors, trans, MAF, etc.).
- Select the A/C option that matches compressor location — or No.
- If Other Location, fill the notes with a clear description (and photo if you can).
- Confirm PCM plan uses an F-Body operating system and that A/C retained/deleted is noted for the tune.
- Do not add the 1999–2002 full-size A/C Update Kit — that is not for F-Body.
- Acknowledge custom build / no return or exchange, check lead times, then order.
Pre-order checklist (A/C-focused) #
Before checkout or emailing support:
- Correct Direct Fit SKU: H800 / H750 / H700
- Factory HVAC retained or deleted
- Compressor location known (factory / other / none)
- A/C dropdown choice matches that location (or No)
- Understood: Direct Fit uses factory A/C wiring when A/C Yes is selected (including compressor wiring)
- Understood: F-Body operating system in the PCM is required for A/C
- PCM is 09354896 or 12200411 (either works)
- Understood fan wiring is not in H800 / H750 / H700 engine harness
- Not confusing F-Body options with the 1999–2002 full-size A/C Update Kit
- Order notes ready for “Other Location” if needed
- Photos ready (compressor location/bracket if asking)
- Read custom-build / no return or exchange
- Checked current lead time
Scope note #
This guide covers choosing Direct Fit A/C options and related factory A/C expectations for:
- 1993–1997 LT1 F-Body Direct Fit (H800, H700)
- 1998–2002 LS1 F-Body Direct Fit (H750)
It does not replace:
- HVAC manufacturer diagrams if you somehow deviate from factory HVAC
- A/C shop work (evacuate, charge, leak repair, condenser/evaporator mechanical diagnosis)
- Full Direct Fit non-A/C option selection (injectors, transmission, etc.) — see the F-Body Direct Fit Harness Setup Guide
- S-10 Direct Fit A/C — see the S-10 Direct Fit A/C Setup Guide
Troubleshooting (clutch won’t engage, fans won’t come on with A/C, overheating with A/C on, blows warm, etc.) can be added in a later update.
