I have no personal recollection of checking timing on that platform. Here's where Alldata says where the connector is located. It appears it's by the Air Filter and Battery. The wire looks like it's a Light Green/w Red tracer wire, and it just needs to be grounded.
Why make it simple, when it will work equally as well complicated.
I have an old incandescent test light handy for sketchy situations like that, because it's much less likely to cause damage than a ground jumper. No harm no foul in this case ... maybe you hit the tach lead or something. All the Mitsubeatme-based timing connectors I can remember were a single wire connector with a male terminal.
I jumpered the wrong wire on a Mitsubishi truck about a year ago. It killed it and wouldn't restart. Fortunately it was dropped off for the day so I could fix it quickly. It blew a fusible link behind the passenger's kick panel.
I blame it on my colorblindness that I jumped the wrong one. I think one is green and one is gray.
Good judgement comes from experience. And experience? Well that comes from poor judgement.
