Features
- PRO550 V8 Complete Harness is a harness designed to install a FuelTech FT550 on mostly any racing V8 application. It comes setup for 8 EV1 injectors.
- It comes pre-terminated to suit a V8 engine with all relays and fuses for a simple 3 wire battery hook up and ignition power. It has a 37 pin firewall connector to make installation an easy task and with the modular construction, adding individual coils is as easy as connecting add-on harnesses utilising the built in output connectors. Each connector has its own label and the connectors and harness insulation is heat, moisture and oil resistant.
- It has most of the engine sensors pre-wired: TPS, hall and VR crank trigger, hall and VR cam sync, fuel pressure, oil pressure, wastegate pressure, turbo back pressure, coolant and intake air temperature, driveshaft and more.
- Comes pre-wired for our EGT-8 CAN
- It can be used directly with a distributor type ignition or with additional auxiliary coil harnesses to have coil per cylinder ignition such as smart coils or the FuelTech FTSPARK CDI unit with an additional harness.
- This harness is setup for two nano wide band o2 conditioners and two o2 sensors. You can also use an additional adapter for a dual channel Alcohol o2 with NTK o2 sensors (requires Bosch to NTK adapters).
- There is an INPUTS connector to custom wire up to 5 additional input channels for the engine or chassis datalogging (i.e. transbrake button, suspension travel sensors, input shaft RPM, staging button and much more).
- There are 2 additional OUTPUTS connectors to wire custom outputs like wastegate boost control solenoids, transbrake solenoid, dump and lockup valves, gear shift, nitrous stages and more.

Winner !!!
Color: Orange
This amazed us. For perspective, we're talking about a three year old white german shepherd who if he's in the mood, has and can kill a toy within minutes or oddly enough be gentle with furry balls and carry them around as if they are his babies. He's an odd duck. Anyway, since he was a pup, and to this day, he'll play and entertain himself, he'll grab a ball, throw it up in the air, then pounce on it as if it's from outer space. It's really quite cute and funny. Because of those two things I was looking for something interactive that would entertain him and confuse him....let's be honest, watching a confused dog is one of life's great pleasures. I tried two other interactive balls and they were crushed immediately. After reading a lot of reviews, people with german shepherds said this ball actually had a life span. I thought the third time could be the charm and ordered one. Well, I think it actually may be from outer space because he's obsessed with it and hasn't taken a bite out of it. He hasn't once chewed it or even teared little pieces off. The three settings are great. Sometimes he likes one better than another, then forgets about the others. I'll change it up to one he hasn't seen in a while and the whole game starts over again. He'll throw it up in the air as he does with his others, watch it and try to figure out which way it's going to go. And yes, he will pounce on it if he times it right. The size is perfect, it's heavier than your average ball but, that's what make it sturdy. I have to sneak it away when he isn't paying attention to charge it, otherwise he'll sit, stare and cry if he knows it's on the counter charging. It's a lot of fun for all of us. I'm so happy I bought it...... I say give this ball a chance even if you have a beast with killer instincts. I'm buying another for a friends 2 year old golden retriever granddog. Thank you Cheerble.

Great toy
Color: Blue
Great toy, too bad my Shih Tzu is afraid of it. I love the way the movement is subtle and random.

I wouldn’t recommend this for strong chewers.
Color: Orange, Color: Orange
Is it fun? Sure. Was it easy to charge and set up? Yep. That being said, this toy kind of fell flat for me. It really didn’t do any big movements once charged that I expected it to, so that was a bummer. I initially got it for my dog, but my cats were more interested in this than my dog was. The battery does seem to last a long time and the motor is pretty quiet. I WOULD NOT recommend this toy for strong chewers as the material for this is a foam rubber and I don’t think it’s durable enough for strong chewers. While the material makes this ball extremely lightweight for more movement, a strong chewer would have this disintegrated in five minutes flat. My Dog is a super strong chewer. I don’t think I would feel comfortable leaving him unattended with this because I know he would destroy it.
