No. On this page every electrical part fits both the 3.7L 225cid L6 and the 5.2L 318cid V8. You do not need to pick an engine to choose the right row — use the notes for position and trim.
What are the signs of electrical problems on a 1966 Fargo A100 Van?
Common symptoms include slow cranking on cold mornings, a battery light that flickers, dim lights at idle, or a check-engine code pointing at a sensor circuit. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.
What should I replace at the same time?
Where labor overlaps, clean or renew the battery terminals and grounds with any charging-system repair.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 1966 Fargo A100 Van was originally sold in the US, the safest choice is a part marked for the US market.

Every part on this page already fits both the 3.7L 225cid L6 and the 5.2L 318cid V8. Then test before replacing — a failed alternator and a bad ground can look identical, and sensors are frequently condemned for wiring faults. The notes column carries position and trim qualifiers where they apply.
