I know that the Speed Density setup for the LT1 swap is easier, so I'll go with that. My question is: Does the wiring harness year matter when converting to SD? I mean, should I look for a '93 LT1 harness as opposed to a later year one? Since the '93 F-Body was SD. Would this ease the install?

 

How do you figure SD is easier? Whether the harness is SD or MAF has nothing to do with how easy the swap is.

 

Well I've heard that when swapping, the computer is just converted to SD not to have to worry about the MAF. I was just wondering if the SD harness was different than the MAF. Or if it made a difference?
Also, does the '93 T56 tranny harness differ from the '94-'97 T56 harness?

 

Get a MAF harness, worse comes to worse unplug the MAF and the PCM will go off SD. Its not a good idea to get a lt1 and just go SD. You'll see better results with a MAF.

 

Well there's a LT1 harness with T56 harness attached on ebaymotors for $50. So you're sayin' just pass this one up and find a MAF harness? Do the harnesses usually come with the T56 harness if it's form a 6-speed car?

 

THe engine harness on any LT1 will include the connections for the transmission, even the 4l60E harnesses. Just get a 94+ harness. The 93 Auto harness will be different since it uses a 700r4. I know your using a t-56 but thought I would note that.

 

Ko man. Thanks

Not trying to jack the thread...

But Pasky, to do the intake swap with an existing sbc and 700R4 I should still get the 93 harness?
The LT1 intake I have is from a 94 Z.

Thanks,

 

Im not sure bud, I have no idea about doing a SBC to lt1 intake. I was under the impression you just need the fuel injection part? I may be wrong, because thier is alot more on the lt1 harness, like MAF, knock sensor, and crap like that. But if your going 700r4 I would think you need a 93 throttle body since it has the provision for the TV cable.

 

No, keep your stock harness. Everything that you already have is the same for the intake.

 

No...
I have a TBI engine right now.
So I need either a TPI harness or LT1 harness.
Which do you think is better, and what year should I get if I do decide to do this?

 

Yeah sorry man, didn't know that when I replied. As far as I know, you won't need an LT1 harness. A TPI harness has all the same hookups because it has all the same sensors. You just might have to lengthen a couple of the wires.
