Anyone else: Old car was converted to 12V years ago — wiring is a mess

CruiseMom94Community StarterMay 31, 20261988 Toyota Land Cruiser FJ62Ohio
Picked up a classic that was converted from 6V to 12V by several previous owners. It works, but the harness has splices everywhere. Would you repair sections or start over with a modern fuse panel and new harness? If I fix it I'll come back and update the thread. Ambient temp was about 84°F when I noticed it.

Hard-won lesson from my last deal: Ask for out-the-door on the 1988 Toyota Land Cruiser with fees, add-ons, and rate on separate lines. Do that before you talk monthly again. On “old car was converted to 12v years,” that was the fork that mattered for me. Parts cannon is a personality type I try to avoid. This is the filter I use when the thread starts repeating itself. I'd rather look cautious in this thread than stuck later.

Treat this like a math problem, not a vibe. Keep sale price, trade, and financing split on the 1988 Toyota Land Cruiser so a “good payment” cannot bury a worse deal. If they balk, that's your answer. This is from a 1988 Toyota Land Cruiser in Ohio. If it doesn't change the out-the-door or the repair estimate, it's noise. Might be overthinking it, but I'd rather overthink than overspend.

Fair point. Counterpoint: If one piece looks too good on the 1988 Toyota Land Cruiser, hunt doc fees, accessories, and the APR next. That's the part that actually changes the decision. Time, temperature, and whether it's in gear are the notes that actually help a shop. I'm keeping receipts and dates in one folder.

I'd push back a little: Two 1988 Toyota Land Cruiser quotes only help if both include tax, title, and the same options. Then the comparison gets honest. Post the numbers (or the code) and people can get more specific. Not letting add-ons ride along because everyone does.

I asked about old car was converted to 12v years again and they still won't put GAP/add-ons on their own lines. If the story changes I'll post the new data.

Get the messy numbers in writing first. Keep sale price, trade, and financing split on the 1988 Toyota Land Cruiser so a “good payment” cannot bury a worse deal. Do that before you talk monthly again. On “old car was converted to 12v years,” that was the fork that mattered for me. This is from a 1988 Toyota Land Cruiser in Ohio. That's the whole play. Wrote this up on my lunch break.

If they get vague again I'm shopping the deal elsewhere.

Asking because it changes the advice: If one piece looks too good on the 1988 Toyota Land Cruiser, hunt doc fees, accessories, and the APR next. Then the comparison gets honest. Post the numbers (or the code) and people can get more specific. Not wiring anything in the meantime.

If I were shopping this, if one piece looks too good on the 1988 Toyota Land Cruiser, hunt doc fees, accessories, and the APR next. Then the comparison gets honest. This is from a 1988 Toyota Land Cruiser in Ohio. Time, temperature, and whether it's in gear are the notes that actually help a shop. Worth doing even if the car feels fine right now. If they only talk monthly I'm walking.

If I were shopping this, two 1988 Toyota Land Cruiser quotes only help if both include tax, title, and the same options. That's the part that actually changes the decision. If you share a photo of the worksheet, easier to sanity-check. Doing the boring step first on purpose.

Walked a dealership this week on the 1988 Toyota Land Cruiser and the doc fee was the tell. Sleeping on the number either way.

Insurance and tax belong in the comparison, not as a surprise. Keep sale price, trade, and financing split on the 1988 Toyota Land Cruiser so a “good payment” cannot bury a worse deal. If they balk, that's your answer. On “old car was converted to 12v years,” that was the fork that mattered for me. Write the result down so the next test isn't a repeat of the last one. If they get vague again I'm shopping the deal elsewhere.

Walk if they won't put it on a buyer’s order. If one piece looks too good on the 1988 Toyota Land Cruiser, hunt doc fees, accessories, and the APR next. That's the part that actually changes the decision. Time, temperature, and whether it's in gear are the notes that actually help a shop. Going to compare one more dealer before I decide.

I'd want competing paper, not competing stories. GAP, paint, and nitrogen are optional until you run the 1988 Toyota Land Cruiser numbers without them. I'd rather lose the car than buy a foggy deal. If you share a photo of the worksheet, easier to sanity-check. This is the version I'd tell a friend.
