    2 Pole Plug Housing wire terminals?

    I can't find any info on what terminal type I need to get for the 2 pole plug housing (PN 12521706091). I'm replacing my fuel injector terminals with these but I need the terminals PN to get the wires into the plug housing. Someone help!

    Ok, I've found the answer. the 2 pole plug housing for our cars is PN 12521706091, it is a Bosch EV1 type Fuel Injector connector. These connectors are also used on many other sensors on the car including the coolant temperature sensor. These plugs do not come with the electrical contacts so you have to order those separately. The electrical contact PN is 61131357705 and shows up on ecstuning as a genuine BMW part for a whopping $3.43 PER CONTACT. After a little bit of research I found that these bosch connectors are pretty common so you can find the electrical contacts from non-bmw sources. I ended up purchasing the contacts for $0.45/per from http://www.240turbo.com/blackvinyl.html and tested them out last night to fit perfectly in the housing. I'm headed out tonight to harbor freight to hopefully find an 'open contact crimp tool' to do a professional job on crimping the wires in the contacts which I recommend to anyone else doing the same job.

    Ive used connectors from Injector RX in Houston with good results. They come with up to 8 pigtails assembled, ready to go for less than $5 each. No reason to buy anything else.
    Good Luck
