Thomas. i just bolted in my P11 trans today.
The switches are different. Way bigger (thread wise)! The connectors are weird too.. the only ones similar on a B12/13/14 have only one guide on each side (like the injector connectors) and these are a dual guide on each side... very different but good design i think....nothing Ive ever seen on any 80s-90s Nissans cause Ive looked in the junkyards. So as far as them just plugging right in... it aint happening.
Also the neutral is way in the front as opposed to the rear so it will require wire lengthening anyway. The reverse wont cause its right by the LSD and the stock connector (resembles the O2 sensor female) will reach.
A cheap way to do this would be to just solder in 2 wires to the switch port and the other 2 spliced in where the harness connector used to be, fill the switch w/ rtv or a big piece of heat shrink over it also so nothing shorts the pins. Thats a ghetto but functional solution. not my route...
i already have one connector and plan to find the other to splice both switches into my B13 harness. not really too hard. I can solder and run wire blind folded
Finding the connectors for the switches is the toughest. im guessing anything B15 and newer will be the only cars to source these type of connectors if we are lucky so keep an eye out for wrecked or parting out P11s and B15s maybe even spec- vs regardless of engine size or tranny configuration!!!
. Chances are these types of connectors are used elsewhere too like emissions junk, etc etc..
Nissan loooves to recycle connectors.. i found a Z32 MAF pigtail equivalent in a 87 Stanza Minivan. Different color wires.. but same connector
just an example
On a side note i was able to just bolt my P11 trans right up. I didnt have to grind the shifter rods and they clear and operate perfectly ( the striker rod was grinded and it looks almost perfect). the P11 trans has a really tight feel thru all the gears. I did notice however, that sliding the whole shifter linkage assembly back about a 1/4 to 1/2" helped everything fit better too. Very clean and simple install. ive had tougher times w/ a se-r trans thats for sure...
Feel free to PM me if you have more specific ??s or something..
Ill take pics tomorrow all I have to bolt up is the rear mm and starter..
a glorious day in the garage for me today
