--NP205 electronic VSS speedo sender

[littlejoe83]

I runinng a 94 chevy 350 TBI at fist I didn't think I needed a speedo sender but to run right and pass smog it is need
This is a ford 205 and the VSS parts are from a 241c


Start with taking off the rear yoke and housing



Take off the old speedo gear



The 241 "gear" is about .250 wider







So I had to cut it down

[littlejoe83]

For the new gear to clear the housing I had to mill the inside where the old speedo sender plugs in





Milled a flat spot



Cut an 11/16 hole and taped to 3/4

Wtf is wrong with you guys ?? He's actually making something work himself instead of paying someone to do it! That to me is way cooler then some stupid fags that run part....

Thank u very much!! There is nothing like having a beer with the radio on in the shop getting ur hands dirty on ur own rig using ur own ingenuity!! And this would be a better place if we all did a little more of that and sharing and less busting balls

Thanks again and I hope this will help others later

[bweezy]

some people just have to bitch...

time is money..ya you spent a few hours on it..but it was free and you did not have to wait a week for it to come in the mail. if your like me i would rather be in the garage making something because its what i like to do.
good job

If you didn't point that out I was sure as fuck going to. Good job, great to have access to a mill and lathe

I like it! I've been wondering how the heck I can get my speedometer to work in my 97 after I put the 205 in it. I couldn't find anything on that website for 97.

[Jason4x4]

i like it, but I don't have access to all that fancy stuff, so I got it from here.

and here i am hiding that useless 91 4l80e and np205 combo out in the shed...

[littlejoe83]

Thanks again guys and yeah this is one of those thing.. It's not what u know its who u know.. My cuz has a a shop and lets me go play after hours if I pay him off with beer haha

If I ever had time I would offer to do if for people that needed it and had the parts to ship me.. Not now but maybe one day I'll get my gold star and offer it up

As for my deal I should be putting it back together this week ( I am waiting for seals)

Except that the ones you listed will not work. I've been down this road and tried to use several different sender kits, and none worked properly. The problem is that the above is a 40 pulse per rev signal, and JTR offers a 2 or 4 pulse that is meant to go directly to the ecm, not to a drac module.


I did exactly as shown years ago in my own rig after trying the easy way out with senders that didn't work.

[abigassbowtie]

hey little joe you must have done this quite along time ago cause i copied this same idea a year or so ago off the internet

dont know what website it was on but must have been you

[abigassbowtie]

nope pretty sure its not you

this whole thread needs to be added to the FAQ. i like the ingenuity my hats off to the OP for his machining prowess, but for those of us without access to such equipment the links to the different speedo providers is good.

Youre correct. They dont work with the drac module, which isnt required for the ECM or the speedo. Ditch the drac and yes they do work. Ive done several conversions TPI and TBI using the JTR VSS.
One wire from the VSS goes to ground and the other directly to the ECM, while the cable drives the speedo.

Except if it's not a engine swap deal, then without the drac you lose your cruise, ABS, and if it's a 93 up the trans won't shift.

Hey jersey shore (yes we all hate u cuz of ur spray on tan and down syndrome IQ) but that not the point.. The JTR VSS is an option but it is not what I am trying to show here

Yes u are right.. This way u can plug it in and every thing works the way it was ment to

[Odin K30]

What are ya trying to show then?
This is nothing that hasn't been done before.
So don't hurt your arm patting yourself on the back.
