Checking Dwell - No Diagnostics port

[Gstretch2001]

Hello everyone. I purchased my first D about a year ago, early vin, automatic. Sitting since 1987. over the last year I have completed most of the major stuff. pulled engine and trans,ingition system, fuel system rebuild, sealed everything back up etc, etc. surprisingly, it started right up on the first try after I put it all back together! However, it is not running perfectly. I have fixed all vacuum leaks and checked for the recommended issues on the forum and now I want to check CO, but dont have a diagnostics port (belive me I dont have one). does anyone have any advice on how I could hook up the dwell meter?

Connect one side of the meter to the orange wire and the other side to the block as ground. The orange wire should be in the engine bay somewhere (Blue Bulkhead connector, pin 20) but can be traced back to its origin on pin 17 of the Lambda computer. The lambda computer is located in the ECU compartment behind the drivers seat opposite of the fuse/relay compartment.

You can tap in on pin 20 of the blue bulkhead connector
