Wiring AC using Coyote Engine Controls Pack

[2bking]

The M-6017-A504V Engine Control Pack contains an AC relay that can be used to power the AC blower and clutch. There is a wire included that can be used to operate the radiator fan when the compressor is running. The link below is a Ford Racing Drawing explaining how to connect the AC relay and rewire so the PCM gets the AC request command (for idle increase I assume).

The AC wiring that is referred to on last page seems to be missing.

Basically all that is needed is to ground the grey wire looped in the harness at the C-47 connector when needing the AC relay to close. The DB/WH wire on pin 4 of the ILC (In Line Connector) needs to be connected to the grey wire to signal the PCM for AC request.

The output of the AC relay goes to BEC pin B-6 which isn't populated. Some type of lead will need to be attached to the pin to get access to the output. I'm thinking a small spade (female) can be used or a lead soldered to the pin and passed through the connector will work. Otherwise, the proper contact for this connector will have to be found.

The radiator fan can be turned on when the AC clutch is engaged by grounding the TN/RD wire from connector PDB BEC, pin A-12, through the Trinary switch. A fan over ride switch can be connected to this wire. Grounding this wire turns on the fan.

edit: The AC relay is fused at 15 amps so another relay will be needed for the blower fan. The Whitby fan has a running current on high speed of ~8 amps with a surge of over 35 when starting. Lock rotor current is 65 amps. The 15 amps from the AC relay can operate the compressor clutch, ~4.5 amp, 4 relay coils of ~.2 amps each, and the heater coolant valve coil using about 4 amps.

Thanks for this. I was searching the net to find something about it. however, I am a beginner and I tried to understand what you said and I couldnt. is there a simpler way to put it in!? a simple circuit drawing that shows the a/c + and - the fan + and -. something simple please.

Edited: What I found is that

1) the ILC (AUX/ILC to 14C508 Engine Harness) does not have DB/WH wire in pin 4. no wire at all in this pin.

2) the only DB/WH wire I found is giong between PDB 15pin (Female Terminals, PDB - 07) and PCM 70 way ( PCM70-57). (on FFR data sheet it says that it connects to PCM70-57 and BL which I assume that BL means Blunt, however its not there, I checked the blunt wires but no DB/WH). on PDB 15pin (Female Terminals), the DB/WH is double crimped with VT (but God know where it ends!). there is VT Between PCM70-13 and C47 (Female Terminals) C47-11, and marked as BOO but on the male blunt connection no wire wired to it.

3)"The output of the AC relay goes to BEC pin B-6 which isn't populated. Some type of lead will need to be attached to the pin to get access to the output. I'm thinking a small spade (female) can be used or a lead soldered to the pin and passed through the connector will work. Otherwise, the proper contact for this connector will have to be found." (after I do this where should I connect the other end of the wire??)

4)"the radiator fan can be turned on when the AC clutch is engaged by grounding the TN/RD wire from connector PDB BEC, pin A-12, through the Trinary switch. A fan over ride switch can be connected to this wire. Grounding this wire turns on the fan." there is a TN/RD wire on the PDB BEC, pin A-12, (do I need to do something here or you are basically explaining how it works?)

I would really like someone to explain it to me.

Thanks

I was all day looking into this :/. I found this link ( http://www.fordracingparts.com/download/boss302spdfs/2014/electric/CM-14A068-C,%20Controls%20Pack%20PDB%20-%20RevA6.pdf )

I beilieve according to this one all what I need to do is to connect the Wire VT (** Blunt Leads that are ‘Hank-Taped’ into C47 Take-out) to the A/C Trinary switch. and the B6 on the BEC to the A/C clutch. the looped grey wire is already grounded with the #17 Starter solenoid, Battery NEG.

Honesty I have a headache now and I will leave it for the pros to comment.

1) the ILC (AUX/ILC to 14C508 Engine Harness) does not have DB/WH wire in pin 4. no wire at all in this pin.
ANS:If for some reason your harness has this wire, it needs to be moved. The harness that comes with the M-6017-A504 Controls Pack has this change incorporated in the harness with a double crimp on PDB -07 where the blunt lead VT is connected.


2) the only DB/WH wire I found is giong between PDB 15pin (Female Terminals, PDB - 07) and PCM 70 way ( PCM70-57). (on FFR data sheet it says that it connects to PCM70-57 and BL which I assume that BL means Blunt, however its not there, I checked the blunt wires but no DB/WH). on PDB 15pin (Female Terminals), the DB/WH is double crimped with VT (but God know where it ends!). there is VT Between PCM70-13 and C47 (Female Terminals) C47-11, and marked as BOO but on the male blunt connection no wire wired to it.
ANS: You found it where the DB/WH is double crimped with the VT. See 1 above.


3)"The output of the AC relay goes to BEC pin B-6 which isn't populated. Some type of lead will need to be attached to the pin to get access to the output. I'm thinking a small spade (female) can be used or a lead soldered to the pin and passed through the connector will work. Otherwise, the proper contact for this connector will have to be found." (after I do this where should I connect the other end of the wire??)
ANS: This is intended to be the feed for the compressor clutch and should be routed through the AC thermostat switch.


4)"the radiator fan can be turned on when the AC clutch is engaged by grounding the TN/RD wire from connector PDB BEC, pin A-12, through the Trinary switch. A fan over ride switch can be connected to this wire. Grounding this wire turns on the fan." there is a TN/RD wire on the PDB BEC, pin A-12, (do I need to do something here or you are basically explaining how it works?)
ANS: This is for clarification on how to remote control the radiator fan if not using the AC relay. The PDB has an IC relay wired so that the fan is always running when the AC relay is activated. If you are using the AC relay to power other functions such as relays to control blower fan speeds for heater only, this IC relay will need to be disabled, else the fan will run anytime the AC relay is energized.
