    Couple of questions...

    One... Is there a plug somewhere in the wiring harness that goes to the back of the car? (91 Crown Vic) I had the plug melt that goes to the trunk lock release, the tag lights, and want to replace the harness from the tailights forward on the car. I am hoping there is a plug somewhere that you can unplug the rear harness at, to make the replacement job easier. Also, if there is one, where is it?

    Second. I know it has been discussed, but what do you need to do to remove the smog pump? I know the belt is different, (I think it is the same belt size as the alternator belt? 100 amp or the smaller alternator? or does it make a difference???) What else needs to be done? This is for Watchdog's 351 91 Crown Vic. (Converted to a four barrel, to get rid of the variable ventura) Also when we were changing out the fan motor resister today, we noticed a hose off, that goes to the charcol cannister on the right side near the battery. Looks like a 3/8 to 1/2 inch... I know this hose on my car went to the bottom of the upper plenum for vacume... What does it do, and should it be hooked up to a vacume source?

    Third. Does the removal of the smog pump cause a problem with the cats? He doesn't want to cause the cats to go bad.

    Fourth. What do we do with the hose(s) that we remove from the pump, just plug them?? Any help is appreciated! Tom...

    I would suggest a mustang smog eliminator bracket. You can still use the stock belt.

    I think the plug is on the driver side wheelwell for the rear harness.

      the hose to the charcoal canister should go through a solenoid to a vacuum source. Honestly, if the VV is gone and the smog pump is gone, I'd go one step further and remove all of the smog equipment, the MCU, and the associated wiring. Its somewhat integrated into the harness that has to stay, but its not a huge lot of wiring, and removing it cleans the engine bay up significantly.

      Deleting the air pump won't mess with the converters. It dumps air to atmosphere after a few minutes anyway. The air is primarily to warm the converters up so they work quicker. The vacuum lines can all go away. I'd unhook all of those solenoids from a vacuum source. The pipe to the back of the heads and the pipe down to the converters can be capped off with a rubber cap. They have one-way valves but the valves are often an imperfect seal.

      Smog pump is on the AC side. It has nothing to do with the alternator belts. I think its a 56" belt to just delete the smog pump, or you can use the Mustang part to get slightly nicer looking belt routing and retain the stock belt size.

        You mis-understood me... I was told the belt to eliminate the smog pump is the same belt as the other side... The alternator, steering pump, and crank shaft. Was just trying to confirm that before we went and bought the parts. I'll do some cross checking on the size you gave me, tho.... Tom...

          they're different sizes. I think its a 50 for the alt side and a 56 for the other, though the police stuff may use a longer alternator belt. Pretty sure its not as long as 56" tho.

            Thanks for the info. Very informative.

            I will be removing the smog pump this weekend. I would just leave it in place but the pulley had developed a wobble and is starting to make noise. Better to just chuck it and have done with it. The vacuum lines and hoses are easy enough but I am afraid to get into the wiring for fear of cutting and or removing something important. Does somebody have some pics of what has been removed or of an engine bay after the fact I can use as a reference?

            Thanks in advance.

            BTW, Tom posted for me because I was at work. Thanks Tom.

                When I de-wired that 89 Vic, I unplugged the MCU and just followed the wiring. Anything that went to or from the MCU got removed. The only part that I seem to recall being next to useful wiring was the section that went between the two fenders along the firewall. I un-taped the split loom, pulled out the MCU related stuff, and replaced the loom and tape. I dislike having cut wires floating around, so anything that was part of the MCU got removed in one piece. I think there was a connector or two that I partially de-pinned too. Theoretically it could have been put back in as it was completely undamaged. Scott may or may not still have that wiring laying about up there.

                  Smog pump is history. For the time being I just pluged the hose with a bolt held in place with a hose clamp. In a few days when I have more time and can get together with Tom, I will remove the rest of the hoses and wireing. Thanks everyone.

                    Just FYI, the 351 will need the 60 inch belt for smog pump delete.

                      oh, right right. AC sits up higher on a 351.

                        I guess it's different if you have a 351 anyway,
                        But when I removed mine, I did also have to play with different idler pulleys, finally found one just barely small enough to work. The belt size I needed just plumb[or is the expression "plum"?) didn't exist.

                          You want to leave the solenoids plugged in (electrically, not vacuum) if you don't want a check engine light to pop on.

                            no CEL on the 351/VV cars. Deleting the MCU would take care of that anyway. No computer to set a light. The computer on the VV engines does very little. You can take a dead stock one, unplug the MCU, and it still runs fine. All that thing seems to do is open and close the smog control solenoids.
