i have had these sitting around for awhile now and I need to figure out what makes and models these are for. any help would be appreciated.

Let me know if you need better pictures. Hope this works!!!

Thanks,

Can you read any numbers off of them? I'm not any good at randomly IDing them, but I might be able to help narrow it down.

 

1st one is obd0 and looks like a bseries alt 3 pin plug i dont know what the bseries ones look like exactly but im pretty sure the d mounts are straight across
2nd one is a obd1 dseries
3rd is an obd2 dseries square plug
last one looks like a obd1 b but its hard to tell

 

2 are d series, and 2 are b series. one of them is obd-2
