Do not buy an SM harness... That is exactly what someone who owns an SM would say (although I own one too).. but, I have both an E and an SM and have done plenty of swapping of parts between the two, i can assure you there are far more differences than you realize and you will not be happy when you are trying to mate up everything You simply just need to add a new extra, more simple harness for street legal applications. Lots of places sell these, but if you are convinced on doing your own I will write something up below.

As I mentioned above.. the SM harness will have neutral light wiring, clutch wiring, kickstand wiring, fan wiring, entire cluster wiring, a different run/stop switch wiring and so on... The harness is ~$250 new.. used will be ~$70 and up before shipping. And, unless you want to buy all the oem bar/lever switches, instrument cluster, and so on you will be cutting all the factory connectors off anyway and buying new ones. So really, you just spent $100 bucks on wires, and now you have a harness tied into your frame with any number of wires that are not used but are still wrapped in with those that are needed. Need I even mention, that there is the level of effort in removing your existing harness to put the new one in. If you haven't done it before, then I reserve the "i told you so" card for when you start thinking you should have just ran new wires. Why rip out all the current working wiring on your bike just to run lights and a horn? You really just need to take your time and snake some new wiring through on top of the existing ones.

What you will need:
A spool set of multi colored stranded wire for $30 https://www.amazon.com/dp/B00N51OO7Q/ref=cm_sw_r_other_apa_ZOwHxbBZEX0R4
black electrical tape
wire loom if you want it.. lots of black tape will work
If you want to get fancy and connect things up nicely, get a handful of universal auto connectors, nice and pricey ones are "deutsch" connectors but spade connectors will work just fine. all the turn signals are 2 pin. the taillight is 3, headlight is 2 pins per light.. (high and low) depending on which you get. Brake light switches are 2 pins each (front and rear). All the relays are typically spade connectors, and there will probably be 6 of these. You will also need 2 for the horn.

Tap into power anywhere after the ignition switch.. so that your lights only come on when you have key-turned.. there is a number of places to do this then run power to your control on the handlebar.Ground will be from all over, best place is the battery though.

Taillight might as well be powered directly from the ignition.. it comes on all the time when the key is turned. Same with headlight, but you will need to switch that between high and low. this takes care of your rear running light.

Typical handlebar control you should get.. i didnt look long and this one may be a bit pricey, but it has all the switching you need. https://www.amazon.com/Technologies-12-0055-Off-Road-Multi-Function-Handlebar/dp/B000IOO4KK/ref=pd_sim_263_33?ie=UTF8&dpID=414eakRFE3L&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&psc=1&refRID=0XT37ZA8388WFWNJSQQK

You can use 2 relays for the whole setup.

For the headlight.. http://www.oreillyauto.com/site/c/detail/CTI0/84601/N0381.oap?ck=Search_N0381_-1_4631&pt=N0381&ppt=C0335#compatibilityTab_ will work fine. the switch i made above goes before the relay and has two wires coming out of it(one high, one low).. and one common going in.. Connect a +vdc going into the common.. the other two outs will be going to relay.. one for high beams on 87, the other for lows/running + on 86. ground goes on 85. Headlights done.

Flasher relay for your blinkers.. .. http://www.oreillyauto.com/site/c/detail/NOV0/EP34/01546.oap?year=2001&make=Suzuki&model=Swift&vi=1375130&ck=Search_relay_01546_1375130_4631&keyword=relay&pt=01546&ppt=C0117
This also goes before your turn signal switch.. the relay has a power in.. B, and then a ground.. E, then a flashing VDC out, L. L goes to the handlebar common input and the controls have 2 going out.. one goes to Front & rear Left.. the other Front and Rear Rigtht. each turn signal has a ground as a second wire. here is a simple picture.. http://i281.photobucket.com/albums/kk204/freddyflatfoot/Signal0_zpsd66b34a5.jpg.. for the relay i linked, the B is X in the pic.. L is L and the E is for ground or P in the picture. turn signals should work now.

The annoying part of all this will be the brake switches... E model frames do not have the welded bolt holes for the S/SM switches for the rear. Also your front brake levers do not have bolt holes for switches. Yet again, another failure point if you go with an SM harness. To get these working, I would go with banjo bolt pressure switches for both front and rear.. just need to make sure that you get the right size to replace the oem banjo bolts. Here is an example.. (may not be the right size)..https://www.amazon.com/dp/B000GTV0RC/ref=pd_lpo_sbs_dp_ss_2?pf_rd_p=1944687542&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B0039ZTQEO&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=G97BJBWZ2KJBAABS9H7T If you dont go with banjo bolts, you need to rig something up for spring activated switches on the factory E levers, which dont have any mounting points, unlike the SM models. Once you do this, you will run two grounds to the brake light. +vdc will go directly to the light, the two grounds will go to the light via the two switches. When either one of the brake switches is hit.. it completes a path to ground and the light will come on. Brakes are only annoying because of the need to refill your brakes. (good opportunity for steel braid lines! if you wanted them anyway).

The horn works just like the brake.. power to the horn, ground through the momentary switch built into the controls.

Put a fuse or (multiple if you prefer) inline for the wiring you just.. somewhere between the ignition and the components.

Your last bit you need to figure out is a speedometer, and you could get an S/SM cluster to make it easy.. except on money.. but a Trail Tech Endurance is much cheaper ($89.99 new) than a used factory instrument panel and comes with the wheel sensor you need. If you get the striker or vapor you can get a sweet looking indicator panel to go over it that will give you turn signal indicators, and so on (extra wiring needed though). Trail Techs are accurate once wheel speed is set correctly and they are really.. really easy to install. So much that KTM/Berg/Husky uses the same reed switches mechanism for speedo function. If you do this, remove the old speedo cable, plug the hole in the stock wheel sensor up with a rubber plug or epoxy(if you never will use it again) and then leave the sensor there as a spacer for your wheel. I think some sites sell a spacer to eliminate it.. I cannot remember.

Thats it.. You would have horn, signals, headlights, taillights/ brake lights, speedo and you didnt mess with your factory wiring one bit, which means the only thing that will possibly NOT work when you are done is your lights or horn.

I could try to draw up a crude wiring schematic if you really need, or I can answer questions as you do it if you feel it is something you want to try. Either way, I have faith most people can figure this out with some guidance from the forums, youtube, and google.
