Default Will this part fit my Bonneville?

I asked the seller a few questions and and this is what he said..

Yes the pcm is working but I saw ecm on e-bay I bought it for back up and found out for my model its take a different number.I have lesabre limited and it takes 16183247 BMYU and the lesabre is 16194774 BHDU.And I check from GM and that number is correct for the limited.Yes the motor is a 3.8!

eBay Motors: ECM 1995 Buick Lesabre (item 280315786409 end time Mar-01-09 06:18:50 PST)

I have the 1995 Bonneville SE 3.8 motor...

Thanks!

If the connectors are the same you would probably need to reprogram it since it is most likely programmed for the Lesabre

Hehehehehehehehehehehehehe

Yes it will fit, yes it will work as long as it is what they say it is, and it looks like it is.

See that shiny plate area on it, the one they wrote LeSabre on? Take that off with the two screws and swap the blue chip. It'* called a memcal eprom. That'* where your programming is stored.

The eprom never seems to go bad, just the rest of the pcm.

There'll be no need to reprogram or try to program your vin, everything is on that blue chip. Swap that puppy and you are back in the game if your pcm lets you down.

Eproms are static sensitive, so use static discharge protection prior to touching, removing and replacing. Once they go...they are gone and they usually rewrite form a "1" to a "0" in the binary and are nothing but junk afterward. I would recommend a static wrist strap for the procedure Antistatic wrist strap - Wikipedia, the free encyclopedia

I have nothing to lose, I guess...A lot of good info in this thread..I found one unit at one of the local junk yards here in northern California and they wanted $135.00 for a used one...

When did Junk Yards become expensive?

I installed the $35 Lesabre PCM and it worked!!! NO more stallling and the battery is charging a lil over 14 volts on a regular bases...It starts on the first crank...It runs very good for a car that year...

They also must have put a clear coat on the car cause I buffed the hell out of it and the paint is more shiny then my 2004 vehicle with Zero fading at all...

Thanks to everyone who helped me with all of my problems!!

As I said before, this has been the most helpful auto forum I have ever joined...I almost need to buy a Pontiac only cause the resources you people have (this car was my sis'* car)...
