Last year I purchased a an MSD 6t and a Haltech F10X from a forum member with wireing harness and went to a local tuning shop to have it installed. They had to replace the air temp, water temp and map sensor and I was running it on stock 550cc high imp injectors. It was running fine.

While I had my car in storage for the winter I got a Haltech E6X, an electric fan, engine ground kit, I added 720cc low imp injectors as secondaries, and decided to relocate my battery in the back. It`s an FC btw. So I had to extend every postive wire to the battery. ( starter, fan, ecu, fuse box under the hood, msd)

Sunday I put in a new battery and while I was tightening the terminals I smelled something burning and smoke was comming from behind my dash, passanger side. Quickly I undid the terminals and let the smoke clear with the door and hood open. I checked all the positive wires for damage and nothing. I didn`t try to open up the haltech yet. But now I`m wondering what did I do wrong ?

 

Sounds like you miswired something. It's hard to say what as we weren't there when you wired.

However something is very weird...You extended each power wire individually to the battery instead of just using a distribution panel in the engine bay?

 

to me sounds like a lot of stuff was directly wired to the battery.

When you put in the new batt, I believe you do postive first then negative, if you do it a certain order can't it fry things?

Tis also possible you put the batt backwards, I did that for 2 sec and got some smokin wires

 

Well when I replaced the secondary injectors with low imp one's I just soldered the wires to where they were supposed to go on the haltech harness. Do I have to add resistors or change a fuse in the fuse box ?

And when I put the battery I put negative first then positive. And I'm sure I didn't reverse the poles.

And also I've never heard of a distribution panel. That's why I extended every wire to the battery.

 

I'm using stock high imp 550cc as primaries and low imp 720 cc as secondaries

 

It's my wireing harness that bot burned. From the main relay to the main haltech connector. So now I'm looking for a Haltech main engine harness for an EX6

 

The fuse box in the engine bay... I believe is what aaron cake is referring to. You just need to bring one 2gauge wire to the engine bay and rewire it there as if there was a battery there :P
