Obd for e30

I have a 1985 318i. It starts fine and immediately stalls. I've replaced a ton of parts. No joy. Not interested in a stomp test because i understand i need to solder in a light in the cluster to perform it. I am sure the old plastic will explode if i touch it. I would rather use the diagnostic connector. My question: it's a 15 pin and one apparently doesn't exist. Does the 20 connector fit into this 15 pin as it appears to the same as the 20 with a side removed. I would need to buy one and didn't want to waste money on the wrong connector.

I bet its a vacuum leak after the AFM. Had the same problem with my 2.7 I had. It'd start up rev up a little bit then immediately die. Sealed the intake boot with electrical tape and solved my problem.. so I bought a new boot the next day and it ran good again.

As far as I know.. no diagnostic connector. That 15 pin connector is only for resetting service life of your oil and pads I think.
