Re: 241OR Rock-Trac/Teraflex 2-Low/Novak Cable Shifter Install

Ok with all the talk of speed sensors, does anyone have an answer on how to connect the 3 wire VSS connector on the tcase to the 2 wire connector on a 91 4.0/AW4?

Thanks,

Not quite sure on this. Would you happen to have a FSM? If you could figure out what each of those two wires are, I imagine you could connect it somehow. What color are the two wires?

I mainly wanted it to for my database, and to make sure it was 4:1. Keep us updated on what you decide to do with your case. I'd like to know.

Has anyone held a 241 SYE tail housing up the the JK 241 tail housing to see if the bolts line up to see if that route might work. Also JB Conversions has NEW JK 241 4:1 RocTracs on sale for $1299!

SOB!!!! I must have a knack for picking up a good deal, and then finding a better one literally days after.

Wow I guess so. That is one hell of a sale. I wish I would have paid $600 less when I purchased mine. Sheezus.

I don't have a FSM. The wires are black and white.

Re: 241OR Rock-Trac/Teraflex 2-Low/Novak Cable Shifter Install

I swapped the 241OR in my XJ a couple weeks ago with Seiler's help. My speedo was reading about 15% fast like Seiler's. So, I ordered the dakota digital speed calibration box this week since it is the cheapest option, and installed it yesterday. Someone linked the SGI-5 dakota digital unit earlier in this thread, but here it is again.
http://www.dakotadigital.com/index.c...rod/prd126.htm

They're in SD, so it only took 2 days to get mine since I'm in CO. I did talk to one of their techs to make sure it would work, and he told me there shouldn't be any problems. So away we go. Installation is straight forward. Much like the Superlift TruSpeed.

- Splice into the speed sensor signal.
- From the tc to the interface input (didn't need to connect the speed
sensor gnd).
- From the interface output #1 to the ECU.
- Connect to a good ground.
- Find a switched 12V source in your fuse panel. I used #17 per the Superlift instructions using a single auxilary fuse holder from autozone.

My dipswitch settings are:

DS#1 - ON
DS#2 - OFF
DS#3 - ON
DS#4 - OFF

I calibrated mine while driving using a gps, so I didn't do the calculations (even though they are easy). A quick drive down the road, hitting the down buttons a few times, and I'm spot on again.

Put a meter on the 2-wire connector to find out what wire is what. You know for sure at least one of them is the signal. I'd be willing to guess the other is power. The black wire on the 241 is the speed sensor ground, so you should splice in a ground wire to connect to the chassis somewhere.

Good to hear Cam. I'm glad it all turned out OK.

Thanks for the info. I'll have to give it a try this week and get back to you.

Re: 241OR Rock-Trac/Teraflex 2-Low/Novak Cable Shifter Install

I wanted to say thanks to all of you for all of the great information on this thread. I am in the process of figuring out what I want to do with my truck and this thread helped a great deal.

I was going to upgrade my current transfer case but feel the extra money is worth it to get the 4:1 ratio.

Seiler (as well as everyone else) thanks for the thread and all of the info!
