I'm in the middle of installing a few Haltech bits and can't find a nice place under the hood for my TCA-8 amp. Where is everyone putting them? I hate that they put the connector on top.  

What length leads did you get on your EGT's?  I've got the amplifier but not the EGT's yet as I want to confirm where I put them first.  My plan is to either put the amp next to the ECU somewhere or if there's not room there or will make too much mess with wiring into the cabin I'll be putting it inside the passenger side (left side) front guard.

I bought WHP thermocouples from ecumaster. They are much cheaper then Haltechs and come with weld bungs and compression fittings. Not certain how long the leads are, but long enough to get anywhere sane. 

 

Haltech states the amps are not completely water proof so I'm going to avoid front guards. I don't want to put it in cabin to avoid the nest of wire. Rather pass 1x canbus cable into engine bay then 6x TC's into cabin.

I’m thinking of putting mine either behind the abs unit or in the passenger guard 

I have a catchcan where abs usually is, if not that would of been a great spot. I'll probably make a bracket and put it somewhere in that region.

Do you not have wheel arch liners?  It should be pretty well protected back there.  Can pretty easily waterproof it if need be.  Wrap it in a plastic bag.

Throughout my career as an electrician and then an electrical engineering technologist, I have yet to see a plastic bag wrapped in electrical tape waterproof anything. It has the opposite effect, water gets in and stays in. 

I agree, It should be rather well protected with liners, but I like to err on the side of caution.

Hey, I'm no rocket scientist or electrician but I do know water doesn't flow up hills very well.  If you affix it vertically with the cables coming out of the bottom of the sealing bag (like one of those waterproof phone swimming bag thingies), the insignificant amount of water that gets passed your guard liners isn't flowing up into the bag provided it's half well sealed.

But anyway, your car, you do what you see fit!  🙂

It can actually flow up into it. Capillary action up the cable into the bag.

I appreciate the ideas though. Sorry to come off strong, bagging things is just a very hot topic in my field. A lot of old timers did it and it's one of those things we scream inside when we see because we know when we remove it to do it properly, you'll get covered in rusty water and whatever surprise it hides will be corroded. 

Cheers!

 

Aren't these small enough that they could reasonably fit on the front side of the passenger's suspension tower? Where the PS reservoir and airbox live. A little judicious relocation of the loom plug that resides there should see enough space made.

Or how about on the firewall above the ABS unit?

Unfortunately with the Type K connectors at the bottom and the canbus connector on top, you need a fair amount of space. I tried both locations you mentioned with no luck. I'm either going to make a bracket to space it out near your yellow circle or near the right headlight. 

Cheers.

I would be interested to know what did you do at the end ?

THanks

I'm a tad late to the party but here's where I ended up installing it. One oem hole, bracket to another oem hole I also use for PS reservoir.

I used a 90Deg strain relief instead of the straight supplied on the 8pin connector. 

Cheers.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
