These are the diagrams to install 98+ gated shifter. Spent 2 days to figure these out.

*** This wiring is for SC400 gated shifter, SC300 gated shifter might be different, I don't know since I never had a SC300 gated shifter assembly***

*** I might be able to do a SC300 gated shifter DYI if someone is able to send me an SC300 gated shifter assembly.***

The O/D will disengage if you shift it into " 4 "

Look at that tangled mess of wiring. lol. Very nice work, I'm going to keep a copy of this in case I decide to do this mod later. I'll also add it to my DIY collection.

 

^^^ Yeah sure.

 

WOW!!!!! Thats a lot more work than i expected! how long did it take?

 

It's not really a lot if you do it.

Those wiring are for the gated shifter , O/D , ECT, and lamp.

Looks alot from the diagram but really it isn't...

 

Nice work- gated shifter install is not that hard to do-great upgrade

 

Yes!!! I finally got it working!

This mod is for my SC400 it should also work for SC300.

As for my SC400 stock shift linkage, I shortened it by 1 inch. Yes I cut it and rewelded by a bodyshop!

The indicators from my cluster lights up too! Awesome.

I could have done this in a day but the wiring took me 2 days since I don't have schematics.

Will post pictures soon.

 

SC400 shift linkage.

SC300 might be different, I'm not sure.

THANK YOU.

doing this mod this week

 

Easy for you right?

 

You can reuse the bolts from your non gated shifter to hold the shift linkage to the new gated shifter.

 

Excellent...should be a piece of cake for everyone out there wondering how...

 

I love you.

 

Took me 2 days to figure out the rest of the wiring.. Well here you go... easy wiring for everyone.
