This is for a 1992 Mazda B2600i, but should apply to any EFI B-Series. I noticed my connection to the MAF was intermittent, would notice the engine run poorly if I just moved the wires coming in to the MAF plug. After looking around extensively and even ordering the wrong plug the first time, I finally came upon this: [url=:1sh1h95m]Bosch 6 Pole Connector Repair Kit (Bosch Part Number 1928402603, in case the Amazon link goes dead in the future)

You will need a set of ECU Pin Terminal Wire Crimpers, similar to this tool: [url=:1sh1h95m]Delphi Packard Five-cavity Wide-range Crimping Tool 22-12 AWG / 24-14 AWG

The holes in the back of the connector are wide enough that you don't need to do a super precise job of crimping like you do to repin an ECU, so overall the install was easy. And it's super nice having the quick disconnect plug now instead of that aggravating pry-with-screwdriver style connector from the 80s.
