Hey Benny, a couple tips on wiring: First, you shouldn't twist wires that are going into a crimp connector. When the little wings on the crimp fold over into the wire, they cut strands if the wire is twisted. The strands should lay straight and parallel, so the crimp wings slide between and squeeze them, forming a gas-tight connection that excludes oxygen and moisture. Also, you definitely shouldn't solder-tin a wire before crimping it. Over time, solder will do what's called plastic deformation; it slowly changes shape under pressure from the crimp, so the crimp can become loose. In a signal wire, this can cause intermittent signal, and in a current-carrying wire, it can cause a high-resistance connection that can lead to heat and fire. Finally, a properly crimped connector does not need solder added after crimping. In fact, soldering can reduce reliability because any solder that wicks up the wire, inside the insulation, will tend to stiffen the wire. Under flex or vibration, this can cause the solder to crack, breaking the wire right behind the crimp. Anyway, awesome project -- I'm looking forward to seeing some quick passes!

is it possible to get a copy of the wiring diagram and cheat sheet? would be a huge help really enjoyed watching this build

[@pauljohnson7382]

After watching all of the connections/pins that you had deal with while rewiring...Benny...I'd be sitting in a corner of the shop rocking back and forth with a little bit of drool dangling from my chin...love this build series! 👊

Excellent job. Not many people know just how difficult it is to do what you have just done. These days a mechanic is 99 percent auto electrical. .

[@bumblebimmer]

I met Benny in Vegas a few years ago. I was stunned. Dude is super chill.

[@fredericrike5974]

Haltech is going to be on the leading edge of the electronic/electrical aspect of the "car culture". More and more companies are fielding "wiring kits" with pin out sheets and revised wiring diagrams than ever before. The days when you had to deal with some arrogant snot more interested in "protecting his domain" than opening the sport just a little bit are coming to an end. Hurrah! Benny, your calm presentations don't hurt a bit! Had to put the kibosh on Lemon Squashes, but popcorn is still on the table- for you, I'll always make more!

[@bradrhodes7809]

Super interesting to watch! I just today finished off wiring in a Link G4+ Altezza PNP ecu with wiring adapted to suit to my supercharged IS200 today and dropped it off to the tuners! I went with link cause it has the ability to control the OEM throttle body motor system and the plug headers match so it’s a direct plugin, just needs repinning. Once all this corona isolation stuff is over I’d love to meet up with you at a sparesbox skid pan or something

[@lochun91]

i have used ecumaster det3 in Fuel Implant mode on mine is200. i run a slightly different charger, as i have mercedes m65(45cui per rev, you have 62cui per rev), i'have added fuel return line with supra mk3 7mgte FPR, rx8 red 350cc injectors, and 155mm drive pulley. flow rartio is simmilar to yours on same pulley, cause my charger have lot smaller wheel. no the numbers part, 237hp on the crank and 292nm, we didnt touched ignition yet, but we will. you can easily go same way :)

Fyi! The thermo fan isn't controlled by the bcm, it has a temp switch on the radiator so when it gets to the desired temp it switches the relay, it is its own circuit.

Benny, could you please explain how did the car idle normally? Im planing to do a throttle motor delete on mine but i have no aftermarket ECU so im a bit anxious it won't idle. Yours seems fine as stock but I have absolutely no explanation for it! Please bless me with your enlightenment Saint Benny!! 🙇🙇🙇

[@MindBlowerWTF]

@@nickhodgman offbrand splices arent usually normalized, so they get brittle after just crimping. You can heat them to anneal them and they will work much better - crimp nicer, stay just as tight and not break after fatigue.

[@petervanderhoek8971]

Gday! Where did you get the crimp joiners? I've been trying to find them for ages! (the ones you are using around 6:50)

[@johnmcf]

They’re called brass docking connectors, I spent ages googling random words till I found them!

[@nitrothunder9937]

Hey benny, What you're doing here would it be hard to do on the Lexus is300 with a manual swapped transmission they come factory with a 2jzge vvti and am personally looking at doing a +T and piggyback or standalone setup on it. just am curious if the process you're going through with your is200 would be similar or if I would need to do a lot different compared to you.

Need to invest in a bucket seat and bigger wheel, it'll make it heaps easier to slide smoothly.

That was Benny's first time installing an (aftermarket, obviously) ECU? I'm actually surprised.

[@markbithrey3635]

What are them terminal connections called? The ones you used to wire the ecu in

[@1one3_Racing]

I'm not 100% on this, but they look like the centre pins from a standard pin connector. They are a non-insulated blade connector. So he's crimped them male/female and then later will install them to the plug.

[@markbithrey3635]

Yeah I know what a non insulated crimp join is but these don’t have terminals

[@markbithrey3635]

Nope not the ones I’m talking about the ones he used to splice in the haltech to the is200 ecu is what I’m after I already use the deutche connectors they are awesome

[@deimantas2754]

i guess haltech learned to make their components waterproof after martys subaru got flooded many years ago

[@ifgezroxy]

It's a bit different situation, when the whole electronics are submerged, with a port for tuning forgot open. That is what pretty much happened to super gramps.

Ben have you talked to your mates at Sparesbox about being a sponsor of our Shitbox Rally car? As per the rules of Shitbox the car can't cost more than $1000 so I need some bushes and tie rods donated. It for cancer research so it's tax deductible and good advertising! 😅

[@1one3_Racing]

We have LOTS of them in Australia. It's a charity rally. Same as Gambler 500 in the States. You have to buy a 2 wheel drive worth less than $1000, it needs to be registered (which is tough in Australia) and then we drive them 4000km on terrible roads across the centre of Australia and at the end sell them. We are raising $6000 for Cancer research and annually the rally raises over $2m. It's a bunch of fun and for a good cause but it's stressful as hell! We're so far behind on fundraising and the car (2000 Jaguar S-type) is total garbage. My grandad died of lymphoma 2 years ago and it was just horrible, so I'm doing my bit.
