Default Extra plug on Denso Compressor - Same model

I got a new compressor and after getting the old one off. (BTW, it was a bitch to do). I noticed an extra wire plug on the new one. Exact same model as the old one. Any thoughts?

Hey

I had to work on my compressor recently, i bought a second hand one and just replaced the clutch and soldered it onto the old unit. i had thought about replacing the whole unit but knew of how much of a pain it was going to be so well done for going down that route. So, I saw many same part numbers at much reduced costs compared to the xk8 specific one. What car is yours for? I am presuming it isnt speciifc for the xk8 otherwise the cables would match. Is there much difference between the cabling?

The 97 cars monitored a lock sensor on the compressor (similar arrangement to the ABS sensors).

From 98 on this monitoring was dropped, so the sensor was no longer required. AFAIK that is the only difference between the compressors, so I imagine that you can just tape the redundant connector up out of the way.

that's what I was thinking but the last thing I want to do is have to pull this darn compressor out twice. I sent denso question I hope they get back to me there's no call in number for consumer support. This is what I sent them :

I purchased "Denso - with Clutch A/C Compressor 471-1382" from Walmart. I used your product finder to find the correct compressor for my car. When I pulled out the old compressor I noticed the new one has an extra electrical plug coming out of the bottom that by old one did not have. My old compressor was also a Denso. Some information from my old compressor is: HFC134a, The number 447200 is on the label. There is a barcode with the following number also on the unit: F111694. Is the new unit I purchased compatible with the car. If it is, do I just ignore the extra plug?

A brand new Denso, made in Japan with clutch is only $160 bucks. I would be nervous screwing with an old unit since the labor getting the thing out is a pain. I have an 99 xk8.

JEPC shows Jaguar part MCA7300AD (Denso 471-1382) up to late 1997, then MCA7300AE (Denso 471-1358)



I got the Jag/Denso cross reference from the Densoproducts website but Denso proper shows the 471-1382 as applicable to both. Take a look at the website here:
Find My Part

You can see a "360° spinset" of both compressors. One has the extra lead, the other doesn't. There's also a downloadable pdf of the installation instructions if they didn't come in the box.

HTH

That is really interesting, I am not sure if the extra connector will cause an issue. For my 1999 the Denso part finder only brings up the 471-1382. It does not bring up the 1358 until 2000. However my VIN is SAJGX204XXC035616 which I think is the 1358. I did not get a response from Denso today, I may try and see if I can find some unlisted number to figure this out, I am ready to finish this job!

I talked to Denso and a Jag dealer turns out Denso's lookup is wrong so every aftermarket lookup is also wrong. I suggested to Denso that they fix the issue and the rep just laughed and said maybe I have a late 1999. I told him mine was manufactured in 98. I am sure he will not try to get them to correct the info. I am sure I will not be the last to have this hassle.

Makes me wonder where the additional information comes from. Densoproducts seems to know the subtlety, as does Motorcars limited since their site also shows the 1382 as applicable to the early cars, Even the local motor factor's lookup (I was in there this lunchtime collecting some parts) quoted the 471-1358/MJA7300AE/DPC11003 for my 98.

I suspect that you would be fine with the 1382 other than needing some extra sticky tape...
