A few 5 speed swap questions (and build thread)
 

I’ve been considering doing a manual swap on my 97 recently and have a few questions for those that have done it

I’d really like to get an entire donor vehicle but finding a junk 5 speed within a reasonable distance seems almost impossible, so is there any source where I can buy the engine wiring harness and ecu? And do they have to be from a 97 or would a 96 or 98 harness work? How about from a Tacoma? I understand the ecu plugs are different between the years but would that still be a problem if I am using the matching wiring harness?

Another thing I wanted to know, could I use a Tacoma as a donor vehicle, they seem to be more plentiful, but would things like the pedals and drive shafts work?

And finally will this be drivable with my Aussie locker or should I consider going to a selectable, I really like the lunchbox locker and the street manners are excellent but I’ve heard it can be harder keep from chirping tires with the manual

Thanks for any advice, I’m just trying to determine if I should keep looking for an appropriate donor vehicle or just piece together components from junk yards as they become available

I would recommend finding a donor vehicle. That way you will have every part you would ever need for the swap. You would probably want a 96 or 97 as they changed a lot of the wiring in 98. You can swap the whole ECU and engine and dash wiring harnesses or change the ECU connectors and repin them. Either way is quite time consuming. Swapping the whole harness means taking the dash out, but guaranties that everything works, because everything just plugs in. You should be able to find some rusty gold in PA for a few hundred bucks.

The rusty gold is disappearing around the state.. I seen quite a few people doing 5 speed swaps. It's a shame Toyota removed manuals as an option in their 4 runner lines. :[

this is true, while junk 4runners are out there manuals are super rare, which is why i was interested in using a tacoma as a donor since they are more common. I check craigslist and facebook daily, and I'm willing to travel a fair distance

I agree about being disappointed that toyota doesn't offer a manual in the new ones, if there was a bare bones manual model offered i would go and get a new one, but until then I prefer the older ones

Off of a Tacoma you can use:

Pedals
Clutch hydraulics
Bellhousing
Transmission
Transfer case (as long as it's the right one you want or a j shift)
Shifters
Clutch / flywheel
Front driveshaft
Floor boot plate
Possibly wiring harness/ecu if you match it up

You'll still be missing

Rear driveshaft
Interior trim piece

Part of the reason for being more rare is because only 2 to 3% of the last years up to 2000 were manuals sold in the United states. :[


Keep us posted. Why not create a build thread for your conversation? That way you have a timeline for yourself. :]

Thank you for the help everyone, I will definitely start a build thread when I start this project, I probably should have started one already but I haven’t taken any pictures of the stuff I’ve done and my 4runner is really a rusty old jalopy compared to a lot here, but the good news is it drives and runs amazingly since I have way more than it’s worth into it so I might as well swap in a manual since I’ll be keeping it for a long time

It's slowly coming together, I drove several hours on saturday to pick up swap parts from another forum member

unfortunately after reviewing the wiring diagrams, which I am completely unqualified to interpret, it looks like the ecu and wiring harness I have (from a 99) won't work, so if anyone needs those parts for their swap project send me a PM

so in the meantime, can I just wire up the neutral safety switch to the switch on the clutch pedal, connect the reverse lights, an drive it like that with the check engine light until I get around to getting a 97 ecu?

Yes, you will be able to drive it with your auto ECU after the swap with minor wiring alteration, but like you said you will have a CEL. Unfortunately, the manual / auto ECUs from 1997 had completely different connectors. If you don't have vehicle inspection or smog in your state and you don't mind the CEL then no problem, but if that's an issue then you need to either re-pin your wiring to the new manual ECU, or swap in a wiring harness from a 1997.

I will probably end up repinning the harness and getting an ecu from eBay or something since I really don’t want the CEL but I’ll be able to live with it for the time being

Yes it will run like that. You will have to run your own wire as there are no wires in the dash for the clutch Park wire to switch at the bottom of the clutch to any ground nearby. Step on the clutch and it engages the starting circuit by grounding that wire. If you have a clutch start button you can do it at the same time but it needs to be a 96-97 because they changed to a 4 pronged switch in 98

so I just need to run a single ground wire from the neutral safety switch to the switch on the clutch pedal?

In essence yes, There are 5 or 6 wires on the park /neutral safety switch so you need to get the right one and you can take it from inside the dash where the engine harness connects. run that single wire to one side of the clutch switch and the other side gets grounded to the body nearby. kolelt did a nice writeup on it and he also has a 97 like ours

So i've got an aisin clutch kit on the way from rockauto and I'm taking the flywheel to get resurfaced tomorrow afternoon. for right now I just plan to wire the neutral safety switch to the clutch pedal and hook up the reverse lights and drive it like that until I can get the proper ECU, I hope to start removing my auto trans this weekend

Clutch kit arrived, flywheel is getting resurfaced, may start pulling the auto trans this weekend if I have time

In other news, I now have functional cup holders

Also another forum member who is local to me is going to help me out with my ecu and wiring harness situation. Does anyone know if it is worth it to get the dash harness as well, or if I should just splice the switches for the clutch pedal and clutch start cancel into the existing dash harness? Is it as big of a pain as it looks to pull a dash harness?
