I'm modding a 99 harness for a friend and can't remember what a couple of connectors are. I noticed that this section gets a lot of questions, so I figured I'd start this thread and we can all populate the list and sticky it for future use. BTW, the connectors marked "(Connector CXXX)" are the ones that you'll use to hook up to your chassis for your speedometer, tach, reverse lights, ignition, etc.

1. Rear O2 (Passenger)
2. Reverse Lights
3. VSS
4. Reverse Lockout
5. Rear O2 (Drivers)
6. CAGS
7. Unneeded ground strap
8. Front O2 (Drivers)
9. Unneeded ground strap
10. Alternator
11. Coolant Temp
12. MAF Sensor
13. TPS
14. IAT
15. IAC
16. Injector (Drivers)
17. EVAP
18. Injector (Drivers)
19. Injector (Drivers)
20.Coil Connector (Drivers)
21. Injector (Drivers)
22. Knock Sensor
23. Ground (Rear Drivers Head)
24. Ground (Rear Drivers Head)
25. Ground (Rear Drivers Head)
26. Oil Pressure
27. Cam Angle Sensor
28. MAP
29. Injector (Passenger)
30. Coil Connector (Passenger)
31. Injector (Passenger)
32. Injector (Passenger)
33. Injector (Passenger)
34. EGR
35. AC Compressor
36. F-body Specific (Connector C230)
37. F-body Specific (Connector C220)
38. AC Pressure
39. Front O2 (Passenger)
40. Oil Level Sensor
41. Starter Trigger Wire
42. Crank Angle Sensor
43. F-body Specific (Connector C101)
44. F-body Specific (Connector C105)
45. F-body Specific (Connector C100)
46. Starter Trigger Wire
47. Red PCM Connector
48. Blue PCM Connector

 

3: VSS / Speedometer
4: Reverse lockout solenoid
6: CAGS solenoid (Skip shift)

How many pins is #42? I may be able to fill in a few more gaps tonight. I just pulled a 2002 T56 harness over the weekend and labeled most of the connectors.

In a related question, I'm currently looking to find the other side of the connector for numbers 43-46. I would like to make the harness a simple plug-in into the swapped chassis and want to do it right, not hacking the other connector end out of the donor harness. Does anyone know specifically what these connector types are called and where to find them?

 

Thanks, I updated my post. I'll have to check this evening to see the wire colors for #42. I believe it is the crank angle sensor, but didn't want to put any data in that I wasn't 100% sure about.

I believe #26 is the oil pressure sensor and #22 is MAP. The cam angle sensor is also #27 or #28, but I'm not positive.

When I did my first harness I looked around for the other half of 36-37 and 43-46, but couldn't find anything. I ended up removing what I didn't need and used Delphi Weatherpack connectors to tie needed ones into the chassis.

 

Great idea; I'll play

#17 - EVAP
#22 - EGR
#26 - Oil Pressure
#27 - Cam Sensor
#28 - Map Sensor

#40 or #42 are the oil level and crank sensor (I can't see them well enough to know which is which)

 

#34 is the 99-00 egr? thing that mounts on the passenger side head.
#40 is the crank sensor
#42 is the low oil level sensor

 

Thanks guys, it looks like we have everything marked now. If anyone sees any errors just let me know.

 

46. Starter Trigger Wire
41. Starter Trigger Wire

How come both do the same thing? in my opinion 46 is the correct one, 41 is wrong, it just looks like it... lol

 

Sticky This :d

 

They are the same wire. One end goes to the starter, the other end went to your key switch. It has a disconect on one end so you can remove the harness from the vehicle without tracking that purple wire all the way to the fbody fuse panel.

Also, #34 isn't the air pump, its the egr solenoid thingy that mounts to the passenger side head on the 98-00 model engines.

 

I'm precisely at the point where I need this type of information. Please keep the thread alive. You guys are great!! Thanks a bunch,

In the spirit of completeness, does anyone know the differences for the 4L60e harness? I'm assuming the vast majority is shared, although there will be a few small differences.

 

Can someone ID the color of the wires for the VSS #3?...

thanks

 

VSS wiring.

 

Thanks. PPL/White and LT green/Black..

 

The auto harness is pretty easy to spot because it has a big fat tranny connector on it. I don't have any pics of one though since I've never really messed with slushboxes.

 

BTW, could one of the well informed perhaps circle the connectors not typically used and the ones that are optional (like AC). Or circle the ones you need, if that's easier.
Very much appreciated,

Andy1

 

If you aren't concerned with emissons testing you can remove the following connectors. You will need to tune these features out of your PCM however.

1. Rear O2 (Passenger)
5. Rear O2 (Drivers)
6. CAGS
7. Unneeded ground strap
9. Unneeded ground strap
17. EVAP
26. Oil Pressure (not read by the stock PCM, just goes to the gauges)
34. EGR (only included on 99-00 harnesses)
42. Oil Level Sensor (not read by the stock PCM, just goes to the gauges)

Also most of the wires in the "F-body Specific Connectors" will not be needed.

 

I have a spare automatic harness, but due to the fact that I am working 6 nights a week, 12 hours a night, I don't really feel like dragging it out to take pic's. Maybe someone else will have one they can post pic's of.

 

How about the F Body Specific connectors? Can I/should I remove those as well? May be silly question, so don't flame...........

Oops, sorry I didn't read carefully enough.
Now, you said "most of the wires" are not needed; some are? Could you explain?

Thanks,

Andy1
