so i have a 88 FJ62 that im putting a chevy tbi 350 out of a 88 suburban im using the 700R4 that came with the 350 and using the advanced adapter to mate the 700r4 to the stock fj62 transfer case, so the help i need is the vss that came on the suburban was on the gauge cluster so it looks like my option is to put a vss on the speedometer cable, the vss that goes in the adapter will not work because the stock transfer case is a slit case so it wont read true when it is 4wd low. so what do i do i have not found one that will work. help please
fj62 chevy v8 VSS HELP!!!!!

Your two best options:
1. Get an inline speedo cable sensor from JTR - http://www.jagsthatrun.com/Pages/SpeedSensors_Speedometer.html
2. Don't bother with the sensor, and just leave the wiring alone in the harness in case you want to fool with it later. You will probably need to use a standalone lock up wiring kit for the 700R4 though.
Most swaps I've driven and owned that omitted the VSS ran fine and you never knew it wasn't there until you hooked up scanner to the ALDL port and noticed that the ECM reads 0 MPH all the time. Also, the ECM will throw a harmless check engine light due to the missing sensor, unless you have the ability to reprogram the ROM in the ECM.
tl;dr - get the JTR sensor.

well the other thing is the one that goes in the adapter is like $280. so i would like to do the inline one but from what i found the two pulse one are for a square speedo and not the toyota ones i dont know if just need to get a custom cable and mod the end of the sensor or what let me know what you all think. thanks

and the vss controls the trans as well so even though it would not be in 4wheel low a lot i think it could hurt something but i maybe wrong
I used a Dakota Digital SEN-4165. Mounts next to the driveline behind the TC. Outputs either a 4k or 8k signal. I believe yours should need a 8k signal. And its only $40. Done!

that would work great but 92 and back chevy tbi are a 2 pulse or 2000 pulse per mile and looks like it will only do 4 or 8 i think i just found one on jagsthatrun that will work i had to call them but they said they have one that is a 2 pulse that will go in to my toyota transfer case

but its $110 bucks and not $40 like the one you showed me
well, the one i have is just an arrangement of magnets that mount to the drive shaft and a pickup mounted next to it. You use a certain amount to obtain the pulse output you desire. I think you might be able to use less and get a 2k output. Just search and see if anyone has done this. You might also be able to have your PCM flashed to accept a 4k VSS input.
