402 big block solenoid wiring

[Bigblock50]

I’m installing a new starter/solenoid on my 1972 GMC Sierra Grande with a 402. Starter is in and the “S” wire is attached. Problem is how to route the big plus cable. The solenoid in crammed into a compartment made by the starter below it and by the block and dual exhaust header above. Access and visibility are poor. My first attempt resulted in hidden contact between the big plus cable and the S wire, generating a loud “snap” when I momentarily tapped the ground cable to the battery terminal. So I took off the plus cable pending advice. Would it help to use a right angle terminal on the plus cable?
