I have a sloppy DAPO red positive wires and cheapo aftermarket positive battery terminal situation and would appreciate best solution to tidy these up, make better connections, etc.

This also makes me curious about how 4-6 wires were originally run to the positive battery terminal from the factory.

It's called a battery block positive terminal. At least that is what 914 Rubber calls it on their website. Idk if its available wnywhere else.

I hate those aftermarket battery terminals that clamp down on the cable.


This is my typical “aftermarket” solution. I change the connection block out for 1 with a stud. I put a ring terminal on the main battery cable going to the starter, and replace the connections on the red wires with insulted heat shrink connectors. In this case I also upgraded the cable going to the starter.

I went with these that I purchased from Amazon. Clean and tidy, well built. Just put the wires into the slots and use Allen wrench to lock in, no connectors to mess with. I think they were like 15 bucks if I remember correctly.

I used an automotive bus bar that I found on Amazon for around $10 on my Subaru conversion that has even more 10 ga wires that need to connect to my battery. Attached Image

I took a different approach by installing a 1 in/4 out fuze block .

I did what @barefoot did - but mine is mounted a bit differently. Same effect.

If I remember correctly, the factory connected wires in pairs to a simple loop terminal that was screwed onto a block similar to what was shown earlier. Even from the factory, not the most elegant solution.

I agree with @Root_Werks, not the most elegant solution. From memory on my 1.8 L-Jet car (which may be wrong) - there are three ring terminals that connect to the block. Two pairs of wires (4 total) connected to two ring terminals from the main harness, with single wire / ring terminal coming from the ignition harness.

A few of the examples shown above represent a cleaner and safe approach to the same issue.

"as was" factory set up

I also did what barefoot did (another slightly different approach):

Black box was salvaged from an old Volvo. It's held to the battery with a big zip tie.

Inside of box looks like this:

No cutting or drilling required.

Q; how did the factory mount those 2 ring terminals to the square block + stud? Hard to tell from the pic. Also, did the factory simply crush 2 wires together in one ring terminal or did they put solder on them before crimping, or simply solder the 2 wires to the ring terminal?

What I'm thinking of using is this terminal I found at Wally World and these ring terminals I had in my stash.

Another option are these 4 way connectors. Are these legit?

This pic brings up another question.

The OG 4 red wires go into the harness bundle, correct?
Then why do I have 6 wires going to my positive terminal?

I think one of the additional wires goes to the FI dual relay. Is power to the FI dual relay supposed to come from someplace else, like the engine bay relay board / plate?

The other is power for the trunk solenoid, I think.

(IMG:style_emoticons/default/agree.gif) somewhat of a "Rube" from the factory, but if maintained they work ok
