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 ? And also it`s not even a year yet that I bought all this and is the Haltech still under guarantee ?

 

What do you mean you extended EVERY wire to the battery?

Please explain more. Ideally, the only wire that should be extended to the battery is the original positive battery cable.

 

Well it's writen in my post ( starter, fan, ecu, fuse box under the hood, msd). Originaly there were 2 wires going to my postive, starter and fuse box. Now I added an electric fan, an msd and a haltech ecu.

 

And by the way I found what was cooking. All the wires from the main relay to the main connector. So now I need a new haltech harness

 

why ??? I still dont know.

 

You don't *need* to run those directly to the battery.

The reason I asked is you may have extended wires in such a way that eliminated their fuses which would allow them (if a short was present) to smoke or catch on fire.........and if that's the case you need to seriously check EVERYTHING over.

 

your msd, fan, hatlech should be going to a fuse. if you look at the fuseblock in the engine bay, you will notice and empty slot that you can use
