Well I am changing over my auto civic 1984 hb to a manual.. from a donor 1984 civic hb.. simple you say.. well I noticed theres way more wires on the auto harness,, LIke at the gear shifter theres 10 more wires,, 14 total.. only 4 on the manual.. at the same place.. and another thing I noticed different was under the hood on the manual trans,, theres a sensor there with 2 wires that I cant find on the auto harness or that trans.., so I pulled the complete harness from the manual car, What a joy taking out the whole dash,, has anyone on here done this ?? checked in the swap section,, nothing there,, so I guess what I am asking,, is do I need the whole harness from the donor car,, for everything to work.. I am changing the cluster, so I have a a shift light, clutch pedels are the easy part,, same with switchn out the trans,, just banging my head over that birds nest of wires lol... Just looking for someone who has done this to say O ya,, DOnt do this or that,, because I did and,, so on.. Please if you have anything that will help..

Ty Rob..

I put an auto trans into my 87 civic (it was a 5 speed). The only reason for all of the extra wires in the auto floor shifter are for the shift position backlight, reverse lights and the neutral/park starter lockout. There might be also be a wire from the shifter to the crude control box (ECU) but technically you'd also need an auto ECU if this was the case.

The extra wires for the manual trans are just for the reverse lights- you could likely save a bunch of time/work by finding the reverse light wires in the shift console and making long jumper wires and splicing them into the wires coming out of the manual trans.

yes i have done this swap. its not that easy but its do able.

you need.
the manuel 3 pedel system all of it. you need the aselerator cable from the standerd, as well the chocke cable. as the auto is all one.
the trans mittion mount is diff so need that mount too.
you can keep the auto harnness from the fuse box to the engine but you will have to take the auto harnnes off the auto engine and put it on the std engine everything should be the same. for connectors.
the dash if your swaping the cluster its best to swap out that harnness.
then you can all so take out all the auto shifter wires they mostly all go to the fuse box. the big black and white wires there 2 of them need to get connected to gether as that the started nutral wires. ( its a good way to setup a kill switch).
you will need the std trans shifter and linkage and modify the floor to hold the std as the auto has a diff size hole.
for the std trans for the wires for the revece lights run to wires for the trans to the revece wires at the auto shifter wires. forget the color codes.
you will all so need to change the fly wheel and clutch if all your doing is the trans insted of the engine as well.

Thank you for the insite into this topic,, Ive got almost the whole donor car stripped.. I took out the whole harness even rear.. Nice to have a spare are the clusters different?? from auto to manual>? and theres a different fly wheel too Joy,,, lol.. oo wow. I spent 1o hours on it today.. well taking off doors,, fenders / hatch,, all glass, front rear bumpers,, front shocks complete asm's and rack,, header is off stainless.. took the complete interiour out.. dash. even heater core. Hood.

I am having a hell of a time with the top bolt rear, manual to engine rear mount,, messed with it for 30 minutes, Not much room in there, Click bang click bang and the guy a got it from was nice enough to oil guard the whole engine bay and underneith,, well I guess it leaked oil for a few years,.. Are the drive shafts Cv's different too?? both boots are tore on the manual and alot of play in them,,, and I drilled out the spot welds for the shifter mount,, I noticed that was different,,Will mig it back in place and cover the auto trans cable hole...

The cv axles are the same for auto and manual.

You should be able to get a wrench on it from the top- just pull some of the stuff back from around the thermostat housing area, or use a long extension and U-joint and get it from the bottom with a socket.
