Help with ProSport Boost gause install on 2011 WRX

[Wussola]

Hey Guys,

I bought a SMY Cluster and a prosport boost gauge and oil pressure gauge. I'm very anal when it comes to installs on my car (as I'm sure most of you are) and want it to look at clean and pro as possible. After opening up the prosport boost gauge package, looking at the instructions and components ... I had a couple questions that I hope those who have already installed this could answer ... and hopefully supply pictures (most important).

1. Where is the best place to install the "Boost Sender" in the engine bay?



2. Do most people install the "T" fitting just off the boost line of the BOV? (as I found in this pic)



3. I wanted to use the "Fuse Tap" (a.k.a "add-a-circuit") component to tap into my fuse box. My local auto store (Pepboys) only sells them in 10A. Is that appropriate to use with the prosport gauges? I've seem them online that go up to 15A and 20A.




Thanks!

4. Also, the wire they supply for the "daisy chain" (to power the second gauge from the first) is not long enough to use with the SMY cluster. What did you guys do to power two gauges? Did you cut and splice the daisy chain from each gauge? to make one long one?

1. I do not remember,but I think the Prosport gauge comes with a galley plug. If not,it will have to be purchased.

You can use the stock sender that is located under the alternator. Yes, you have to take the alternator off. Quite easy.To remove the stock sender you will need a 22mm socket.

2. Yes,that is where you install the T.

3.FYI, you need mini ATM fuse taps.I used a set of 5 I bought on ebay. A lot cheaper that way.

4. I did not daisy chain. I soldered the color coded wires together from each gauge to individual add a fuses.

I installed the exact same gauges. If you want I can take some pics & post later today.

My boost sender is in along the back driver part of the hood by the brake master cylinder.

I did a T right around there as well. It's a bit tighter in that area on the STi though apparently

I can't speak on behalf of the daisy chain. My other one isn't a prosport sadly - just the gauge that came with my lc-1

As rage said - pick up a few of them online and get the correct size. I used one for ignition and one for head light signal I think.

Also the fuse numbers on the STI vs WRX are different Drove me crazy trying to figure out which ones to use. The fuses you will use depend on the color you want your gauges to be. I do not remember the fuse numbers off hand but can look that up for you.

You will also need a coupe of extra fuses for the add-a-fuses.

What amp mini ATM fuse taps did you get?

Pictures would be great thank you.

Is it possible to send a picture. Did you use a pre-existing bolt to secure it? Also I emailed ProSport and they mentioned that they do not recommend installing the Boost Sender in the engine bay do to possible moisture with the scoop on subarus ... anybody have any issues with this?

Thanks again!

I used mini fuses of the same amp of the ones I removed from the car.

Who uses fuses?

The stock sender under the alternator




The harness I made



I reversed that clamp & attached the boost sender to it.

Rage-WRX,

Thanks for the pics ... very helpful.

The 1st pic where you mention the stock sender unit ... is that for the oil pressure gauge? If so ... as stock what is it connected to? For my oil pressure gauge, I got the adapter plate that connects at the oil filter. I thought that would be the easiest and most straight forward set up and what was recommended by ProSport.

You could use the sandwich adapter. Makes the install easier. But stock sender tends to be more accurate.

The stock oil pressure sender is connected to the dummy light on your gauge cluster that comes on when you have a total loss of oil pressure.

If you unplug it though, what happens? Or do you just solder into that line?

Nothing happens. No light.

Thanks for the tip ... bought these the other day. ten bucks for 3 is much better than 10 bucks for 1, pluse looks like you have use any amp fuse with them.
