2G 420A Wire Tuck

[Skyline-Tweak]

I've read a few threads and looked at a bunch of pictures. They were pretty straight forward and easy to follow but now I've run into some issues. My car has 2 computers because of the automatic trans that I swapped to manual. The speed sensor was wired into the automatic TCU as that forum had instructed, so there's no way I could really delete it. So tucking them in the glove box was out of the question as there was not enough room for both of them. Downfall to this was that I wanna keep a stock looking interior. So I've decided the best thing at this point was to lay the computers on the back passenger floor and run the wires under the passenger seat and under the carpet and extend them back out the firewall to the bay. Now I'm beginning to wonder if this is the best way to go about it.. I'm wondering if anyone has any better ideas that I could use. Any ideas where to put the two computers or run wires. I only wanna do this once and still have some type of accessibility to the two computers. Thank you for any input. The red line is my planned route and the other picture is how its laid out throughout the car as we speak but like I said if there's a better idea, I'll use it. All ideas will be considered. Thank you again.

So the only reason for keeping the TCU is for the speed sensor?

Can't you just tap into the pin of the ecu like the manuals have?

I am not familiar with auto to manual swaps and the computer side of it.

The automatic transmission had 2 speed sensors. The input speed sensor and the output speed sensor which each of those had 2 or 3 wires per sensor if I remember correctly. So when the manual came around I had to wire in 3 wires from the manual speed sensor and the forum wasn't really specific on why but it just said where and it worked. It sucks because when I got to the mass mess of wire, I see wires running between the computers and back up the harness to the dash from both of them and there was no organization. The wires weave in and out of each other and it's just alot of tangled mess. So I'm trying to figure where I can hide them, that it'll be safe and out of the way.
