Hi I just bought a new msd blaster coil and 6a box, however my ignition control module is bad and I wasn't sure if the box replaced the module, so I don't have to buy a new module.
and also do I have to buy the msd to gn harness

thankyou

 

The MSD does not replace the ignition module, so you'll need to replace the dead one anyway. Sorry...

 

damn I bought the msd thinking that it was gonna replace the module, damn modules are so expensive, this is the 2nd one that i'm buying and they' re $70.00

do I need to buy the msd to gm harness also

thankyou

 

Yep, you need the harness.

 

The harness keeps you from having to hack up your wiring and makes testing or going back to stock a breeze. It is not mandatory to buy one, but you'd be a fool not to get it.

 

how much do these harnesses usually go for

 

I would have to go to an online site to look it up. I'm sure you can do that as well as I.
